There is no connection to the server, what should I do?

Question

Bitrix24

Hello.
Last week we moved from the cloud to the box.
Over the weekend, a standard problem surfaced for - a red bar and the inscription "There is no connection to the server."
We started rummaging through the nginx settings, push&pull, started looking for the signature code from this recommendation , and eventually found out that the required folder simply did not exist on the virtual machine.
Who solved this problem?

Answer 1

First you need to configure the server itself.
Bitrix VM has a special menu - 10. Configure Push/RTC service .
If you use your own configuration, then you will have to play around with the server a lot, because. no other documentation is provided.
