Fastmail Not Loading

I also had the Fastmail problem — after entering my credentials, the loading wheel would infinitely spin and I couldn't get to my inbox.

Inspect Element > Storage > Delete Cookies and Local Storage also worked as a fix for me, with a caveat. When I logged in with "Stay signed in to Fastmail" checked, this fix didn't work — it still resulted in the infinite loading page. When I cleared my cookies and storage again, and logged in without selecting "Stay signed in", the Fastmail inbox loaded right away!

On 0.99.120.1-beta

letourpowerscombine Same behavior for me. The "Stay signed in" checkbox is the thing that is somehow causing it to not load. Works fine if I don't check it.

Version 0.99.120.1-beta (WebKit 614.1.20)

whee Excellent catch. I wasn't able to reproduce this before, but I have the same problem if "Stay signed in" is checked.

+1 to the above, not checking "Stay signed in" prevents the issue from recurring for me. Otherwise I have to do the whole delete cache and cookies dance every day.

letourpowerscombine thanks for the workaround!

Thanks everyone for this fix, this had driven me back to Safari. I hadn't thought to check here for a solution.

I'm curious if any other Fastmail users have experienced links in emails not working? Issue here. Currently links work for me for a while, but at some point they stop working and I have to restart Orion to get them working again.

colinfleming I can't reproduce this links issue in my basic use of the FastMail web app. So, it will be hard for me to help here.

I see that the FastMail web app uses www.fastmailusercontent.com as a Source. You might try manually adding www.fastmailusercontent.com in Orion's Compatability Mode setiings:

Orion > Preferences > Websites tab > Compatability Mode from the list > click the + icon > add www.fastmailusercontent.com

To be clear, I don't know that this will resolve your issue. I'm just looking for anything that might help.

It also only loads for me when “stay signed in” is unchecked. The checkbox to remember me for two-factor authentication, however, does not cause any problems, so that’s something...

That worked for me

Just want to chime in and say that I had this happen to me as well. Signing in with the "stay signed in" option unchecked worked finally, but I had to manually clear cookies/local storage then login from the main fastmail.com home page.

Definitely super frustrating to keep getting logged out on a regular basis because I can't check that box without breaking the entire app. Is there any progress on figuring out the cause? I only have the Bitwarden extension installed, nothing else as far as extensions go.

bitwalker I have the same issue. The tip on unchecking the "stay signed in" option got me in.

We will be upgrading WebKit in the next release and expect it to solve the problem.

We were able to fix the problem (was caused by improper service worker handling). Fix landing in th next release.

Vlad I'm on "Version 0.99.121.1-beta (WebKit 614.1.20)" and I'm seeing the same behaviour as described in this thread: Fastmail hangs on the loading screen, unless you log in with "remember me" unchecked, in which case it's fine.
