What are you writting about?
You enabled proxy in the icefilms configuration but you did not set address to proxy server in the E2iPlayer configuration.
If you do not have proxy server then you should NOT enable it. I think this is the obvious.
You provided logs where proxy server was enabled and as proxy was used "http://user:pass@ip:port".
You did not provide logs where proxy server was disabled. So,?
After proxy server option change you need to exit from the host and enter again to change take effect.
