Can not connect nodes after some split, please help

[Alexander]

Hello, urgent help needed. I can not pay for subscription due to a lot of restrictions on many levels.

I have drbd reactor on first and second, and a third node without it. The quorum is majority and minimal is 2.
Today for some reason I got a failover from first to second, and now I can't connect first to third. I have no idea how to fix it anymore. I keep third to satisfy quorum in case of network split between first and second. Operational nodes are first and second.
Please help me to get it all together.
