I had the problem when I logged in after work Thursday. Tried the usual stuff - fixing permissions and verifying integrity of the cache without luck. I could login to Singularity no problem.
Finally I did what I tell my clients to do first - reboot. That fixed it for me!
If there are no reported problems then please try the following steps. Please note that this will erase the accounts from the launcher and you will have to relog them.
Close the launcher if it is running.
Please press the windows key + R to open a run window.
Copy and paste the following into the run window and press enter.
%LOCALAPPDATA%\CCP\EVE
Right click on the folder named ‘cache’ and delete it.
Right click on the folder named ‘QtWebEngine’ and delete it.
Start the launcher and see if the issue persists.
From the thread from CCP Mechanic. I did this and the problem was resolved.
I have also been having the problem of being “unable to connect to Tranquility”. The problem started recently within the last few days. I tried Olia Liet’s suggestion, but didn’t work for me. Any thoughts?
