I'm trying to copy folders between remote pod and my local but the rsync command always return the same error: server gave HTTP response to HTTPS client

I'm using oc without troubles behind a proxy (login, get, export...) but the troubles arise using rsync and rsh (interactive shell)

Using the logs of rsync process (--loglevel=10) I got the curl requests that is failling. Running this command via my terminal I got this error

* TCP_NODELAY set
* Connected to ***** (*.*.*.*) port * (#0)
* ALPN, offering http/1.1
* Cipher selection: ALL:!EXPORT:!EXPORT40:!EXPORT56:!aNULL:!LOW:!RC4:@STRENGTH

* Closing connection 0
curl: (35) error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol

I have no idea how to solve that trouble, taking into account that for other people from the same place the process works so fine

Edit

The problem is behind the ssl certificates used. I found another curl call that fails due similar issue but for the others (behind the same proxy) works.

After remove completely my current installation (format disk and install a new Ubuntu 18.04 version) it is still not working. Then Anaconda is not the problem

I have Anaconda (conda server) installed and I think he problem is about the certificate. I uninstalled Anaconda and the error persist but with different values and throw a "Bad request error". Have, someone, troubles using "oc rsync (oc rsh ...)" with anaconda installed?

Edited

Finally is a proxy trouble. I did it from home, removing all proxy settings, connect via VPN and worked. The key issue is I do not where the setting is missing.

Proxy configured: /etc/environment ~/.curlrc with proxy created and removed (for both was not working)
