Hello, everybody.

I have a strange situation. I use nginx upstream fair module.

Here is basic configuration on frontend:

upstream testing {
server some.server.com;
server localhost:8082;
fair;
}

Everything works fine till I want to stop nginx on some.server.com for some time.

After I start nginx on some.server.com there are no more connections to this backend server from frontend. Frontend cannot recover this server to operation mode and only localhost:8082 is available.

Could anyone tell me how to solve this problem? Thanks.
