Ok ZOS I've been discussing this for about a month with Support and yesterday it went worse than in the beginning. So maybe going to forum would help?
So, I've decided to return to the game after like a six month absence. I have two accounts merged into one, firstly I've bought a key for the Launcher and then bought accounts with new chapters in Steam and specified my existing ESO account when laucnhing them. Due to this
I could play both via Launcher and via Steam, whichever I prefer.
Having returned to the game a month ago,
I've downloaded the game from Steam as always, it worked via Steam but when I tried to login via Launcher I've got an "Access Code" window but no Email never came. I've tried changing Email and password, triggered ports both on PC and router etc. but nothing helped. So I've made a ticket [240501-002508] and for about a month the Support was trying to help me, changing emails and sending links for forced changing of the password, but it did not help too, the situation was the same - I couldn't login via Launcher but could via Steam.
Further is proof of my correspondence with the Support.
Yesterday the situation changed. The Support changed my Email for the one I specified and after still insuccessive attempts to login via Launcher
I've decided to try VPN and it did work, no "Access Code" message and successful login, BUT only with VPN, and now I can not login via Steam at all, it does not even start the Launcher neither with nor without VPN, like it has been unlinked or something. My mistake that I did not try VPN earlier, so I can not say could it work with VPN back then or not, but anyway the problem became worse.
Moreover, that ticket [240501-002508] has suddenly disappeared from "My Support" as it was never been there, even though much older tickets are present. I've made a new ticket [240527-001049] describing all this but I would like to speed things up a bit.
So my question is can ZOS actually help me here or I'll just spend couple more months
being in touch and then the game will stop logging-in even with VPN?
The only thing I could do from my side is try to change my router IP address but my ISP can not force-change it, they say I have to shutdown my router for a night and then
maybe the system will assign new IP.
