Its been 4 days, I have also tried the cleanup and redownloaded the snapshot, still same
It should be able to connect to testnet

OKD4.4 compute node failed with "Internal Server Error"

I tried to deployed OKD 4.4 on my home cluster using the following doc =>
https://medium.com/#craig_robinson/openshift-4-4-okd-bare-metal-install-on-vmware-home-lab-6841ce2d37eb
The "services", "bootstrap" and "control-plane" nodes went smoothly (at least the output on screen is similar to those in the doc).
However, when I deployed the "compute" (worker) nodes, it failed to startup with the following error:

ignition[xxx]: GET result: Internal Server Error

Any idea what could have gone wrong?
It seems bootstrap is trying to start/connect to "etcd" on the "localhost" (bootstrap node).
Thanks.

MongoDB Enterprise xxx-shard-0:PRIMARY>
A MongoDB Atlas support staff told me this is due to network connection on my part, but I'm sure that is not the root issue, because I can connect to the server when using other client such as Robo 3T using the same Windows 10 computer.
This issue happens ONLY when using MongoDB shell (both 3.6.2 and 4.0.3) in Windows 10.
It's probably a bug with MongoDB Shell and Windows 10 implementation?
it's a bit late but here, I had this problem when my shell's version is 4.0.5 then I install 4.2.11, it solve this problem. I tried many things with different connection string syntax and it does not solve the problem and still stuck at SSLHandshake error, so I guess if version were same it might solve the problem(mine 4.0.5 and remote was 4.2.11) and go ahead with new version installation(though I still think it's not version problem but I don't know what is). This problem only happen while I was in shell, connecting from the client like NoSqlBooster or Spring seem to work fine. My Robo3T have a problem connecting but randomly, sometimes once sometimes multiple re-trying.

Shiny's websockets don't work on port 80 of an AWS EC2 instance

I have set up a licensed Shiny Server Pro on an AWS server. It seems to work basically, but I would like to change the default port from 3838 to 80, and this causes me grief, probably because port 80 doesn't handle the websockets as I expect.
So after installation the server dutifully delivers the default welcome.html page with the two embedded apps hello and rmd and everything works as expected. Bus as soon as I change the port in /etc/shiny-server/shiny-server.conf from 3838 to 80, the two embedded apps won't work anymore. They seem to load, but immediately after loading they are greyed out and a message is displayed on top "Disconnected from the Server / Reload".
I now believe that this is caused by the choice of port 80. The AWS instance's security group has a "Custom TCP rule" on port 3838 and allows all incoming traffic on this port. OTOH, port 80 is of type "HTTP" and I seem to be unable to change this to a "Custom TCP rule" (which makes sense, sort of).
When configuring the Shiny server for port 80 and looking at Chrome's dev console after loading the demo page I see websockets appear on the network tab, when the page is fully loaded. However, they're there only for a few milliseconds. Conversely, when using port 3838, the same websockets are persistent and are not terminated.
At the same time, when using port 80, a message appears on the console tab that the connection has been terminated:
Thu Mar 09 2017 08:47:46 [INF]: Connection opened. http://10.43.190.69/sample-apps/rmd/

This message is absent when using port 3838:

Thu Mar 09 2017 09:09:30 [DBG]: 4 message(s) discarded from buffer
To circumvent this problem I have also tried using nginx and apache2 as a reverse proxy, with very similar results, so I tried to use port 80 without a proxy in the first place.
Edit: netstat output when shiny server on port 3838 (all good):
/home/ubuntu# netstat -tlp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 *:ssh *:* LISTEN 1451/sshd
tcp 0 0 *:4151 *:* LISTEN 6996/shiny-server
tcp 0 0 *:3838 *:* LISTEN 6996/shiny-server
tcp6 0 0 [::]:ssh [::]:* LISTEN 1451/sshd
netstat output when Shiny server on port 80 (embedded apps not working, no websockets):
/home/ubuntu# netstat -tlp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 *:http *:* LISTEN 11116/shiny-server

tcp 0 0 *:4151 *:* LISTEN 11116/shiny-server
tcp6 0 0 [::]:ssh [::]:* LISTEN 1451/sshd
So I believe nothing else is listening on port 80.
Can anyone give a hint?
Cheers,
