Hi, 1. i install gitea Version: 1.16.8 on a sysnology NAS, everything works fine. 2. from the gitea website i create an org and repo 3. after that i got these instructions: ```auto touch README.md git init git add README.md git commit -m "first commit" git remote add origin http://192.168.2.45:8418/myorg/myrepo.git git push -u origin master ``` 1. the excution ends with error. ```auto C:\myrepo>git init Initialized empty Git repository in C:/myrepo/.git/ C:\myrepo>git add README.md C:\myrepo>git commit -m "first commit" [master (root-commit) 627a0ce] first commit 1 file changed, 1 insertion(+) create mode 100644 README.md C:\myrepo>git remote add origin http://192.168.2.45:8418/myorg/myrepo.git C:\myrepo>git push -u origin master fatal: http://192.168.2.45:8418/myorg/myrepo.git/info/refs not valid: could not determine hash algorithm; is this a git repository? ``` whats going wrong?
