Hi!
I've had the same issue a while, AnyDesk used to work normally, then it stopped working and only works if Comodo Firewall is disabled.
Needing to use AnyDesk daily, this has become highly annoying and I've been looking for a solution, haven't found one yet.
Here is what I've tried so far:
o I've tried changing the AnyDesk connection port.
o Make sure that AnyDesk.exe is allowed - it is.
o Uninstall and re-install Comodo.
o Set the connection port rules in global rules.
o Disable UPnp from the router.
The problem exists in all computers I use, with multiple Windows versions.
I've done the above steps in all of them - the problem still exists.
I need to disable the Comodo Firewall, only then AnyDesk will start working normally.
This is not normal behaviour, the firewall must follow the rules it has been given.
If AnyDesk.exe is an allowed application - Comodo Firewall has to allow ALL traffic connected to it.
The problem must have come with some update a while ago, it seems plausible.
What else can this be called, other than a bug in the Comodo Firewall software?
I really hope Comodo fixes this issue soon.
