Hi @joyous
Here’s what should happen. I’ll go through it step by step as that may be helpful to others too. I’m also on Debian.
Download latest SAFE Browser (NOT the mock routing version) from Releases · maidsafe/sn_browser · GitHub (so safe-browser-v0.9.0-linux-x64.zip)
Unzip and launch the browser from within the resulting folder. The browser should open with a login page.
Click the create account link
You’ll now be asked for your invite code. Go to invite.maidsafe.net using your normal web browser, you’ll need to also be logged into the forum. Click through the options then on “update registered IP” and copy the token. Paste the token into the box in the SAFE Browser and continue
Enter an account secret and repeat (note it down, it can’t be recovered)
Enter a password and repeat (note it down)
Click continue and you should be logged in. The first page will be safe-auth://home/#/
It sounds like you may have some sort of connectivity problems, but can you confirm you followed those steps?
