After uptating to 8.13.3 clone by HTTPS doesn't work anymore (Error500)

Hello,

after an gitlab-ce update to 8.13.3 git clone https://git.some.where/Group/Ressourcen-Management.git

doesn't work anymore.

User@MyMachine:~/Projekte$ git clone https://git.some.where/Group/Ressourcen-Management.git Klone nach 'Ressourcen-Management'... Username for 'https://git.some.where': User Password for 'https://User@git.some.where': fatal: unable to access 'https://git.some.where/Group/Ressourcen-Management.git/': The requested URL returned error: 500

the production.log shows the following entries bevor I have entered the Username:

Started GET "/Group/Ressourcen-Management.git/info/refs?service=git-upload-pack" for 87.*.*.235 at 2016-11-06 14:55:39 +0100 Processing by Projects::GitHttpController#info_refs as */* Parameters: {"service"=>"git-upload-pack", "namespace_id"=>"Group", "project_id"=>"Ressourcen-Management.git"} Filter chain halted as :authenticate_user rendered or redirected Completed 401 Unauthorized in 91ms (Views: 7.3ms | ActiveRecord: 6.5ms)

Git clone by ssh works already....

Additional Information: I have disabled nginx in the GitLab System. Because I use a Apache Reverse Proxy.

The Website works correct.

Whats wrong withs my GitLab Server ?!? I've searched on several boards an forums and found any some ideas, I have tried some of them with no result...

Hope someone knows some help.

Best regards David
