Thanks you for looking into it. I was able to sync svn repositories and view the diff.

i have restored the repository at http://ec2-52-49-69-145.eu-west-1.compute.amazonaws.com/svn/devpoets/

the test instance is at test-7japztksvma2.phacility.com

I tried out phacility and still seeing the same error. I am going to try out creating a new SVN repository and import it. Will also be trying out a git repository.

Other than this i have tried importing from a different svn server but no luck so far.

i just tried diffrent protocol. HTTPS vs HTTP.

yes. used that document for troubleshooting purpose.
