Guild Wars 2

So when i open TP an error appears: “Error_name_not_resolved”
This used to be solved by adding CoherentUI_Host to trusted files. but it’s already added so i dont know what to do besides that

any sugestions?

-power cycle laptop
-then try removing it from trusted files, adding it back if need be, since it was a prior fix
- uninstall reinstall if all else fails, may be due to corrupted data.
