SVN failed to submit data (SVN: mkactivity... 403 Forbidden)

I just received a project and was about to upload the project to SVN, but prompted SVN: mkactivity... 403 forbidden,

 

I checked it online and said yes.

The original SVN operations such as check out are URL case insensitive, but can be case sensitive in commit/delete operations. Therefore, when setting the svn server path, note the case sensitivity. However, I can access the URL on my colleague's machine, which indicates that the Internet is not correct with my environment. It turns out that the configuration administrator only gave me the read permission, you do not have the write permission. After you have the permission, you can upload the file !!!! However, if you do not have the permission, the prompt is forbidden.
You don't have permission to access/SVN/on this server. This error prompt is a bit strange.
