Pritunl Client: Unable to communicate with helper service, try restarting - macos

Can't run Pritunl client anymore. It just keeps showing the same error on my Mac.
Error: Unable to communicate with helper service, try restarting
OS X: El Capitan 10.11.6
Tried restarting and re-installing the app.
The app used to work, not sure when it stopped working as I update most updates which come up in app store.
Has anyone experienced this before? Any suggestions on the solution are appreciated.

After some researching I couldn't find anything useful to resolve the issue but I was sure there was a process which was conflicting with functionality of this client. I decided to Quit applications through Activity Monitor one by one. I quitted two or three known to me applications before stumbling upon a service which didn't take up much memory or CPU resources, called helpd. After quitting that application Pritunl Client started without any issues.

What worked for me:
echo "127.0.0.1 localhost" >> /etc/hosts
and then restart
(I had cleaned /etc/hosts previously and it became a problem)

XCode doesn't login to my account

I couldn't be able to login to XCode accounts using my apple ID. It was working before. When I tried to login it shows an error There was an error connecting to Apple ID Server. But I have logged into the same account from another mac without any issue. Please help me with this. I am using XCode version 8.3.3
try these basic ways may be it will help full
Restart your system,sometimes the simplest turning off and on can
fix this error directly.
Sometimes it happens due to the poor Internet connection, check
whether connection is working properly.
Make sure that the date, time, and time zone are set correctly.
Apple discussion says you should check your firewall and antivirus settings - there may be
a similar rule or setting blocking the ID server
In my case, I upgraded my Xcode and Mac OS to the latest version and it started working smoothly
Charles proxy was the cause for me. Make sure you disable/uncheck HTTP( WebProxy) and HTTPS( Secure Web Proxy) and give it a try

What would cause SSL Certificate errors across all installed OSX browsers but Firefox?

Every attempt to connect to Wired.com is met with a certificate error.
I've checked the usual suspects and even done things that probably have nothing to do with it.
Browsers tried
Safari=failed
Chrome=failed
Brave=failed
Firefox=success
Verified no Chrome extensions interfering (incognito w/ no approved incog extensions)
Same with Safari.
Flushed DNS
Rebooted
Time settings obv correct
I started to get paranoid thinking that something is hijacking my connection, but the only active ports I've got open and connected are... well, supposed to be open. And then the fact that it works with Firefox is even stranger. Firefox is my proxy browser, but it works via proxy w/out.
This is a recently upgraded Sierra machine. I'm not an avid wired reader, so I couldn't tell you if it was happening previously, but I can say I've got 4 other mac test machines here and none of them are experiencing the same issue.
Sierra vs Capitan doesn't make a difference. And this is now going on a 2 week issue. Wired appears to be literally the only site effected. At this point it's more a curiosity at getting to the bottom of this than anything else, since it does appear to be something isolated to this machine.
Also, I think we can rule out a CDN issue. As all my other machines are connecting from this same wanIP.
Man, just absolutely any suggestions for more internals I could go digging through to try and get to the bottom of this would be oh so greatly appreciated. Because I've about relegated myself to keyboard head smashing.
The problem (most likely) is caused due to recent issue at GlobalSign as they incorrectly revoked their cross-certificates. Full statament from GlobalSign: Certificate Revocation Issue
Thanks guys. That GlobalSign certificate was cached.
Removing the cache at
/var/db/crls worked
I backed it up first just in case, but sudo wiping the cache didn't cause any problems.
sudo rm /var/db/crls/crlcache*
sudo rm /var/db/crls/ocspcache.db*

Xcode 5 continuous integration: The Xcode Service is not enabled on the server

I've just installed Xcode 5 and OS X Server and trying to set up continuous integration. I followed these steps but when I try to add server in Xcode I get the following error:
"The Xcode Service is not enabled on the server '...'. Contact the administrator for assistance."
The Xcode service appears to be up and running, it shows as "Available" in the Server app and is accessible through HTTP.
Is there any way this can be troubleshooted?
I had the same problem. It looks like there are network name resolving issues there. Try using server's IP address instead of its name. It worked for me.
Unfortunately, Server.app is strange and it does not directly report issues with embedded webserver. Therefore, if you are running some other Webserver (or something else on 80 / 443), whole Xcode CI will not start properly and Xcode will report this issue.
For me, shutting down Apache and restarting the Xcode Server part solved the issue, yet as I need Apache running on my computer, I'm not going to use CI in it's current state. :-(
Possibly, I have to find out how to change default port for Xcode CI.

Windows service blocking TCP traffic

I have a strange issue. Have a windows service running on Windows Server 2008 that receives files over TCP and saves to disk. Initially service was running as Local System account. It worked ok for 7 days and stopped receiving. From the sender side connection succeeds but send fails. The service blocks forever on receive and connection times out.
I changed the user account to "Network Service" and it started working again for 7 days and stopped. I then changed it to run as administrator. It ran for 4 days and stopped again. Now whatever I try it does not work. Rebuilt the code re-installed the service but same issue.
Does anybody ever face such an issue? is it a virus or something? Is windows blocking it? any suggestions will be greatly appreciated.
Note: If I run it as a windows form application it just works fine. Also disabled the firewall but it did not help. While debugging the code I never see any issues. Because it works as a forms app and also worked perfectly as a service for 15-20 days now.
I figured out the problem. When the issue started happening I ran the Filemon utility and figured that the service was failing to access a temp file created using GetTempFileName().
This seems to be a known issue with Windows server 2008R2 and happens randomly.

Titanium Developer Crashes on Startup (was fine)

Closed my laptop when I left work. When I got home and opened it, it had restarted. Now when I go to open Titanium Developer it instantly crashes.
So I can't even open it now. Any ideas on how to debug this or figure out what is going wrong?
Thoughts of even trying to see a message or any detailed error report would be helpful. I'm pretty new to the Mac world, I'm not even sure why my computer restarted - is there a place to see events or what may have triggered that. Couldn't find anything on their forums about this issue.
I experienced the same instant crash problem and found a post on http://developer.appcelerator.com/question/21121/titanium-crashing-on-startup-on-mac that suggests running this chmod -R g+u /Library/Application\ Support/Titanium - so far so good.
Solved this awhile back, just realized I didn't tie up this loose end. I actually had to reinstall the OS. One of the Os files must have been corrupted or locked. With OS X you can reinstall the OS without reinstalling over your apps or data. So took about 30 minutes to reinstall and everything was fixed!
For anyone experiencing this in 2017 and beyond:
Quit Appcelerator
Load Terminal
appc logout
The Dashboard was attempting to load my cached user stats but appcelerator was rejecting my expired session. Logging out of appc solved my issue.
