Transfer aborted: instance not found

hi everyone. blizz support asked me to post here so you guys can help me figure this out.

im having a persistent issue in wow where i constantly get the transfer aborted instance not found error when trying to switch zones take portals enter dungeons or use hearthstones. alongside that i keep getting disconnected from the game on main screen, with the wow WOW51900328 error, i gotta click the reconnect button at least 3 times.

i already tried basic troubleshooting like flushing dns resetting the ui folders interface wtf cache removing all addons and plugging my pc directly into the main router via ethernet, reseting my pc, but nothing worked.

is this a routing problem between my isp and the instance servers or it comes from the game/ blizzard servers?, because ive seen many other cases like this, some got to solve the issue and some just wait untill some random patch fix for them, forgot to mention that when i use a vpn like cloudflare warp it completely nullify the error and i can play just normal but with higher ms. looking for tips from devs or other players that experienced the same, thanks!

Start with your firewall and proxy settings then, as listed in the

tried disabling firewall, didnt work
