3CX Register Failed

[GSSC]

A user of ours is getting random disconnects and looking further into the log files of the 3CX Windows client we are seeing this error

They are the only user experiencing this issue. What would be the cause/fix for this?

We have re-installed the client several times already.

Per the log you posted, that seems to be the cause. As you mentioned noone else is having the issue, you get to figure out what is unique to that user/machine.

If this is one PC on a network that has other PCs not facing the same issue, the first few things we'd recommend checking are:

• Antivirus/security software. Try uninstalling completely and rebooting.
• any third party software that might be interfering in any way.
• Anything specific to that windows/domain user. Maybe test with a newly created local user.
• Check version numbers and make sure they are the latest.
