Latest update 2.8.1 connection problem C5c

my c5c ptp doesn’t connect to each other when I update them to and above
now I’m on
how ever when i update the master to latest version and let the slave on version
it’s connects normaly
thanks in advance

Hmm, weird, probably not a regulatory change. Seems that there is some sort of issue with the client when it gets updated…

Can you give us any details about the link and it’s settings?
