The integration with Ubisoft Uplay doesn't seem to work for me. I don't have 2FA on my account. I had 2FA on before getting the beta invite for Galaxy 2.0, but then turned it of on my Ubisoft account because I assumed it could cause an issue. But in spite of this I still cannot connect with this service. I'm able to connect to the following services without issue: epic, origin, steam.

Has anyone else been able to connect to Ubisoft Uplay?

Have you found a solution yet?
Been struggling with the same problem since the early alpha ... without even a clue what causes this problem.
I also tried activating/deactivating 2-factor auth, changed passwords a dozen times, checked firewall and NAT-settings, deactivated my antivirus software and so on and so forth ...
I had similar issues with connecting my play account on the Nintendo Switch in the past, which disappeared after a couple of days without any known problem (very unsatisfying)

Sorry for the late response, but uplay is working fine for me now. I'm not sure what changed, but I didn't have to do anything on my client to make it work.
