what's the cause of error 120108 and checksum mismatch

Developers of subversion:

         Hello!

         I encountered two problems.

         Question 1: When update the work-copy failed atfter that update some files success , and tips:

                           ‍svn: E120108: Unable to connect to a repository at URL 'https://%e2%80�. '‍

                           ‍svn: E120108: Error running context: The server unexpectedly closed the connection. ‍

                   What’s the cause of this promble? Network error?

         Question 2: When update the work-copy, tips:

                           ‍Error: Checksum mismatch while updating 'D:\xx\xx.h':‍

                            ‍Error: expected: e14ae03a45fcfb4d754531bb5b38d1fe ‍

                            ‍Error: actual: d67898a0aae70499c71819a747b18a0a ‍

                            ‍Error: Try a 'Cleanup'. If that doesn't work you need to do a fresh checkout.‍

                   “Cleanup” is not effective, how to solve the problem except as do a fresh checkout?

                   And what is the cause or operation leads to this problem?

         
         I hope that you can help me! Thank you!

         Looking forward to your reply!

         Have a nice day!

         Regards！
