This occurs only using firefox. It works well in chrome. I also checked if cookies are disabled in firefox but didn't find anything. I explicitly allowed cookies for this domain and tried to turn off all security features that could be related to that.

Answer questions ramonskie

don't know it this is relevant. but when i upgraded from 4.x to 5.x i received 400 error when loggin in with fly the login url was but the new 5.x way of loggin in is via

this seem to be related due to the fly versions fly 4.x is the redirect_uri and 5.x uses login?fly_port

you think with a simple fly sync it would solve the problem but as you are on fly 4.x you can't because if you want to sync you need to login..

the workarround is use the copy the token and login and sync your fly binary
