Should investigate why it always happening for me after switching context

oc v3.11.0+0cbc58b
kubernetes v1.11.0+d4cacc0
features: Basic-Auth SSPI Kerberos SPNEGO
error: server took too long to respond with version information.

error: server took too long to respond with version information.

Can you help in how you reproduced this issue, I can then have a look.
Is this happening from context switch 3.x to 4.x or vice versa ?

@dgolovin I have added a working scenario with the attached gif. This allows me to perform the context switching between different clusters.
Here I am doing a switch between local 3.x and local 4.x cluster. The actions works seamlessly. Can you please check and let me know.
