[LE-51] an unknown error occurred

Having the LE-51 error as described in this tech support post
My game client is stuck on confirming a display name and I cannot get past this prompt in any way. It appears to be related to the “Account Services Temporarily Unavailable” on the main lastepoch.com site.
Is there any way for support to push my display name through to the game client? My steam and last epoch accounts match my forum username. It looks like the game client is just unable to confirm or accept a display name without communicating through the account services server that is down.

I just had this error today. Seems to have been caused by Steam being offline. Sometimes when I launch Steam right after start up it can’t go online for some reason. Might not be your case.

It sounds like the LE-51 error results from entirely different issues. I submitted a support ticket and the solution to my version of the problem (brand new account that was stuck on the “Enter Display Name” screen) was to just spam multiple random/different usernames. Eventually it let me through and I could play the game. Afterwards, support was able to manually change my display name to match my account.

Was this your first login into the game? I mean When you have to fill up account name?

Correct, it was my first time ever installing or playing the game. The first screen I saw was a prompt to enter a display name for my account.
