from mumble themselves if anyone else is having an issue which i assume you are.
Nick: Thank you for contacting support, my name is Nick. I am currently looking into your Mumble question:
“having this issue with my mumble server. UDP packets can be sent to and received from the server. Switching back to UDP mode. is there something wrong with the server or my end?”
Nick: Currently a network routing location outside of our network is dropping packets and having connection issues for users taking that route to our servers.
xxxx: has this been going on for a few days now off and on?
Nick: We are actively working on resolving this issue, however since it is in another companies hands they have not been responding to us well
Nick: Yes it has
xxxx: ok thanks for the quick reply. i didnt think it was on my end
xxxx: i assume theres no work around at this time?
Nick: I apologize for the inconvenience that this has caused you and your users. Sadly there is not as of yet, as it is a routing location before it even reaches our servers
xxxx: ok. it is what it is. thanks for your time
Nick: You are very welcome, have a great day!
