Can not connect nodes after some split, please help

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.
