Issue Description

Connection over wire works but only the first time I attempt to connect UE and eNB. If I disconnect then reconnect all future attempts until I turn off everything for more than 20 minutes and retry do not work.

Additional Information

docfate111 commented 9 months ago

uefails.log ueworks.zip Here are the logs for the UE when it fails and when it succeeds.

If I reboot the srsue laptop and try again then it works the first time again but not any times after that after stopping UE with ctrl+C
