This is unusual, as we haven’t seen this error in a while! I’ve raised this with our Backend Engineer.

Same issue here.

I am on the US West Coast. I am on Steam.

This error code pops up for me every few missions after mission completion, trying to load back into the Hub. Didn’t start experiencing it until the most recent Anniversary patch.

I can load back in just fine with the same character afterwards. i.e, from the character selection menu.

Their servers must be overloaded when this happens. I don’t know what else is could be?

This still happens to me to this day after completing a mission and loading back into the hub. Well, trying to anyway. It’s random but it happens.

I am on a brand new system too.

Two years later and it’s still an issue.

Your servers are garbage!

Try using VPN, it fixes lot’s of errors for me, sometimes even after disabling it, game still works, but not often.
