What does error msg: "could not find redirect rule to delete port=7480" mean?

Hi

I run OPN Sense on a proxmox Server. There is also a second VM for high availability.
HA works. On the slave system I have sometimes this error message: "miniupnpd 35888 - - could not find redirect rule to delete port=7480". But I'm not sure what I should check. The error message usually only appears on the second machine. Interesting is, I see this error message only at the shell. I have searched in the logfiles, but couldn't find further information.

If anyone could help me with this one. Would much apprechiated.

Best regards
Simon
