Create pull request (Gitlab CE)

Hi! I have some problems create pull request in source tree (v3.0.15) for Gitlab CE. I successful add my "Gitlab CE" account with personal access token. In settings>remote account I select my Gitlab CE account. When I select Repository>create pull request... > create pull request On Web, I get the 404 error (page not found). I get this URL:

http://myserver.local/git@myserver.local/IG/SIIG/merge_requests/new?merge_request[source_branch]=develop

Without the first server name, just git@.... the URL works. How can i solve this problem? Is a bug?
