OCCM GUI - Server Communication Error

tyrone_owen_1 — Wed, 04 Jun 2025 14:06:01 GMT

I'm trying to access OCCM via its private IP address from a management server on the same VNet. I see the following error:

Server Communication Error

Unable to contact server

Try to refresh the browser or to update proxy setting

Set up Proxy configuration to allow Cloud Manager and ONTAP Cloud instances to access the Internet. Enter an empty value to disable the proxy

If I close the message I see a blank screen. If I then refresh the browser I see the same message

Any ideas what I'm doing wrong please?

Thanks

Hi Tyrone,

Sounds like some network issue nevertheless. Can you check if your instance is defined to go out through an organization proxy in the browser. We’ve seen that before.\

Thanks,

Yaron

Rajesh,
It is definitely some network configuration blocking access to a needed website.
Most likely it’s netapp-cloud-account@auth0.com.
Go to Cloud Manager via SSH and check if that url is accessible to you.
Then look at this:
http://clouddocs.netapp.com/occm/en/reference_networking_azure.html

Thanks,

In my case it was an issue with Internet Explorer, using Chrome worked fine

While using chrome indeed works better, we found that in some cases the issue was that the organization proxy towards the network was baked into the IE and that when people installed chrome it bypassed it.

But sure - trying chrome makes sense 🙂

HI Yaron,

Thanks for reply.

I had tried to check if url is accessible or not via ssh.

curl -Is https://netapp-cloud-account.auth0.com | head -n 1
HTTP/1.1 302 Found

Its giving me 302. Looks like resource has been temporarily moved to a different URI.

Can you help.
