Hello everyone,
Wanted to share this and post it somewhere for future posterity
I have had an issue at an SME that I was pulling my hair out forever over: what the motherloving goodness is this stupid error
A stroke of inspiration made me realize that there was a limit on the number of allowed connected devices
Increase that limit, then test connecting your Linux device again (or delete an existing connection if it's an old device), and this should fix your issue
Time to go have a drink
