Every day at the first connection of TESO I have an error 303.
At the second connection no problem.
I opened a ticket (# 240701-003156) but no acceptable solution was given to me except to opt for a static IP (it pays) and to open some ports in my box (which I don't know how to do).
For information, this problem only exists since an update last February. I have been playing for more than 5 years and I had never encountered this problem and the technical department is unable to explain to me why I encounter this problem. My hardware is the same since 2019, my connection is fibrated at 500MB and I have a 1TB SSD dedicated to the game.
If this persists, I do not renew my ESO + subscription
