I found there's a conflict between this feature and url displayed in open external uri dialog. If you open an external uri for the first time then the domain of it will be resolved to cache in map data structure. Like https://www.w3schools.com/c/c_structs.php  For the next time if you open a different uri with the same domain Like https://github.com/coder/code-server/issues it will be resolved as the last uri which has been cached.  The uri displayed here is not correct Before there's no resolvers registered by default so external uri is not resolved but after this feature added, cache will take effect  Hope there's a solutaion for this. Thank you! _Originally posted by @ericzhucode in https://github.com/coder/code-server/issues/5624#issuecomment-1430673559_
