So my VA has recently switched from vamsys to phpvms. At first, i was able to use the acars normally but after 2 days i encountered a problem with it saying that i hadn’t entered ICAO code and showing the boxes yellow even though it was full. And now a new issue has risen with the acars showing that i am not logged in even though the crew site and my API key were both there. This just also occurred with the VA owner and we can’t find a fix. Any help would be appreciated.
here is my current settings page 
What does the log says ? You need to share it to get support
I am trying to help one of your friends, probably the admin for the same error. Simply your server is not accepting requests (according to the log your friend provided), so if you can share your log, which can be found on acars/logs folder, we can have a look and compare it for similarities.
the issue of the acars opening and closing is gone but im having this error again
I explained the reasons of that error to your VA’s Admin…
You have scenery scanning problems. Send your acars log to your admin for support
