Hello everyone,
After upgrading Windows 11 Pro from version 23H2 to 24H2, we are experiencing an authentication failure or access denied issue.
Does anyone know how to resolve this?

Which version of veyon are you using? We have no such problem, with the 4.8 veyon.

End the problem!
(before update windows not problem. master can connect to all client.
after update windows master can't connect to some client.)
For fix this. we "create key pair" and import key to all client. and General>Authentication> Select "Key file authentication" > Apply

Same problem !
Some clients connect and then are no longer visible. Others never connect. Same effect with 24h2 and Veyon 4.8.2
