Always logged out from Chrome

Question

I'm using Ubuntu 16.04 with Chrome 53.0.2785.101, and am experiencing the problem,that whenever I boot my laptop and open up Chrome, I'm logged out. I see a yellow triangle next to my name and have to reenter my password. This happens every time, and I don't know why. I don't delete my cookies etc. after I close chrome, but have to log into every website again (Facebook is pretty annoying because of 2FA).

Things I considered why this could happen:

• I recently changed my password.
• I'm using a WiFi connection (Can't use wired atm)

How do I find out what's the problem here and why this is happening? On my desktop pc I don't have the problem.

Update
This is not a duplicate of After rebooting I need to log in each time in Chrome because the accepted answer didn't work. Maybe I should try one of the others in that thread?

Update 2
After the weekend, I had the same problem again. :( Online account is still connected though, but I was still logged out from every site and my Google account.

Solution

I just had this issue after switching from Gnome3 to KDE5 (Ubuntu 18.04). This answer has helped me: https://askubuntu.com/a/401996/432944

Thanks for the link. I did what the accepted answer suggested. Will reboot now and see if it works :)

Sorry @edwinksl but it didn't work. Had the same issue. Logged out of all services and had to re enter my password.

Can't believe it. A non-accepted, non-voted answer of the thread worked! I just rebooted and am logged in. I added my google account to the online accounts of ubuntu! But I will test tomorrow again to be 100% sure that it works.

Heh, awesome. If it does indeed work, please do consider marking this question as duplicate. :)

I'll wait till tomorrow, and if the problem still does not occur I will mark it. :)

Looks like the answers in the duplicate target didn't work for you. I am going to vote to reopen this question.
