How to check why my Heroku application cannot reach remote host? - heroku

I have deployed heroku application - Ktor server that was working for 2 years and everything was working perfect. Since few days my application cannot access host (https://api.um.warszawa.pl/). It's getting timeout error all the time. API is accessible from my local machine. How can I check who blocked the access and why? Where can I ask for enabling the access again? Any ideas?

I have the same issue. I have had contacted the API team at Warsaw Town Hall - they have told me that City's Centre of Network and Data could set location restrictions on the API due to CHARLIE-CRP alarm.

Try to connect locally to Chatbot but get unauthorized error

I loaded the EchoBot template from Microsoft here: https://marketplace.visualstudio.com/items?itemName=BotBuilder.botbuilderv4
I started a new project and try to run it locally. No MicrosoftAppID or MicrosoftAppPassword is provided.
Then I loaded the latest Bot Framework Emulator v4.7
I connect locally, again no App ID or App Password:
However when I try to send a message I get unauthorized error, why would I get unauthorized error when connecting locally?
The server is definitely running locally and the local URL is correct:
One question I want to ask is the login dependent on any 3rd party URL call? My company security policy is blocking all URL unless whitelisted, so if this is the case, maybe the authentication is blocked? What would be the URL for me to whitelist?
EDIT: I tried it a VM outside of the company network and it works! So something must be getting blocked. Any idea?
I got around it by using a VM outside the company network instead. It's not a solution, but it is a work around. I highly suspect some port are being blocked by company firewall but not sure what so I am not sure how to get it whitelisted.

"an error occurred in the application server (Not found)" message in Android app

I've been handed a Genexus KB to make an SD app for it. But each time i want to try it i get a "an error occurred in the application server (Not found)" each time i've ran it in a real device (connected in the internal network thorugh) or in an Android Emulator (Andy).
I've setted the KB to point to a local DB stored in my computer and i've tried different ways to try it and it keeps with no luck.
What else should I do?
PS: when i run the web version of it, there's no problem.
Altight people, first of all thanks for the help you gave me!
Secondly #fpanizza that link you gave me was very useful, I could use CatLog with android emulator Andy (after installing Andy Rootkit) and I found out that my app wasn't reaching REST services in the server which leads me to #Franklin, who was right to let me know that it had to do with REST services and I've found out later that i didn't had installed HTTP Activation at one of the WCF Services at the .Net Framework 4.5 Advanced Services, which allowed to reach REST services, and now it worked.
You can try setting the server URL with the IP of your server.
Is probable that the local host is trying to access itself, the android device.

Update
I would do what fpanizza suggests on the comment.
Another troubleshooting idea that may bring some light into problem would be to try to access the rest services from a web navigator on the emulator. The idea would be to validate that the emulator/device can "see" the server. Testing outside the app will help understand if the problem is in the app or the server or the connection device - server.
Thank you #Juan.

Azure Cloud Service 503 error outside of instance

I have three mvc 3 web applications in a single web role on Azure Cloud Services. All of a sudden this morning both the single instance in production and in staging give "HTTP Error 503. The service is unavailable." when navigated to in a browser.
I rebooted the production instance but nothing changed. Then I deployed a remote desktop enabled version to the staging instance and logged in. However, strangely when I navigate to the web applications in a browser inside the remoted staging instance everything works.
Looking at IIS server logs it seems there are some issues starting the roles (warning level about the appPoolId being incorrect) but obviously the roles are starting as they are accessible from inside the staging server.
The World Wide Web Publishing service is also running and even after restarting this service the web application is not accessible externally.
Does anyone have an explaination for why the sites are accessible locally but not remotely that would help me debug this issue?
I found out where the issue came from, the bindings that were configured in IIS7 did not include bindings for the actual [abc].cloudapp.net host headers.
I assume that for some reason since some time last night or this weekend the requests seem to come with those headers instead of the original headers for the website. This is really strange but adding these bindings fixed both the staging and production instances and they were available again after this change.

Google API Testing on non 'localhost' named local server

I'm currently running MAMP Pro (osX 10.9.4) with several different virtual servers on my local machine, one for each of my client's projects. I've been trying to connect to the Google API use OAuth and have everything working just fine when 'REDIRECT URIS' is set to:
http://localhost:8888
However, as mentioned I've got several of these servers running,
e.g. 'https://clientname1:8890' or 'https://clientname2:8890'
Whenever I enter those into the API console I just get a 'Whoops' message telling me something has gone wrong Google's end:
"Server Error: Whoops! Our bad."
It seems as though only 'localhost' is allowed via the API for local testing, is there anyway I can set it up so I can test off any of my local servers?
I had to add my localhost to the allowed referrers list to test locally. Without that inclusion, I get 403 Forbidden errors. You probably just need to add clientname1 and clientname2 or clientname1:8890 and clientname2:8890 to the allowed referrers list in the Google Developers Console. Mine's set under public api access, so maybe it's going to be another problem for you depending what API you're using and how you're using it. Hope it helps -

Host unavailable when user is logged off

I am facing a problem that I discovered while I was implementing a small client/host application.
The client side runs Windows 7 64-bit and machine never turns off but user is automatically logged off after 30 minutes of inactivity. When user is automatically logged off the host becomes unreachable, first I thought the problem was isolated to my application, but after som investigation I discovered that resources and vnc server is also unavailable.
The question might be a bit off limit for this forum but I can't find any reasonable explanation somewhere else. Does anyone know how I can keep user being logged off automatically but with the host still reachable on the network?
You need to have them as services.
Are you connecting to some port opened by a server/service which runs as the user? If so, that's the reason. To circumvent, you need to have the service installed/started independently of the user, for entire machine (using administrator priviledges)
