Unable to login to 1Password 8 beta

Had a similar experience. Wanted to try out v8 on the Mac (liked some things, but honestly missed the native feeling), and at first it worked fine.

But after a while, I noticed, that items did not sync anymore. When viewing the trash, I remember reading somethink like "offline" or "cannot connect" or something. So when nothing else worked, I tried logging out and in again. I never got this to work again - I am 100% sure and tried many times to input my data, but it always showed an error.

Similar to the previous poster I have given up on v8 for now, since this bug is to severe, and since v8 interfered with v7 too much, I also uninstalled it for now.

So there seems to be a serious connection issue with v8 for Mac in some cases. Unlike the previous poster, I do not suspect MFA etc. to be interfering here, since the error occurred for me after successfully being logged in, as sync failed. To me, it seems more like a general connection issue to 1P servers, but I cannot figure out why. I do run Little Snitch, but disabling the Network Filter did not help. The Mac firewall did not seem to contain any problematic settings. As all my other devices and indeed v7 on my Mac can connect just fine, my router and ISP should be ok.
