What is current OCP and ODF versions ?
Was either OCP or ODF was recently upgraded ? If yes, from which to which version ?

Also, please take a look at these solutions (same issue) and me know if that works for you:
https://bugzilla.redhat.com/show_bug.cgi?id=2134774#c11
https://bugzilla.redhat.com/show_bug.cgi?id=2134774#c19

Basically,

If OCP/ODF both are 4.11:
1) Make sure running below command returns "/" (forward slash):
"oc get consoleplugins.console.openshift.io/odf-console -o=jsonpath='{.spec.service.basePath}'"

   a) if not, run following command:
      "oc patch consoleplugins.console.openshift.io/odf-console -p '{"spec": {"service": {"basePath": "/"}}}' --type merge"

2) Wait for few seconds then refresh (Ctrl + F5) the browser.

3) If even the hard refresh does not work, clear all cache information from browser, refresh and check once again if tabs are visible now.

-------------------------------------------------------------------------------------------------------------------------------------------------------------------

If OCP is 4.12 and ODF is 4.11:
1) Make sure running below command returns "/compatibility/" (forward slash):
"oc get consoleplugins.console.openshift.io/odf-console -o=jsonpath='{.spec.service.basePath}'"

   a) if not, run following command:
      "oc patch consoleplugins.console.openshift.io/odf-console -p '{"spec": {"service": {"basePath": "/compatibility/"}}}' --type merge"

Repeat step 2) and 3)

-------------------------------------------------------------------------------------------------------------------------------------------------------------------

If OCP is 4.10 and ODF is 4.11:
This is not supported. OCP version "n" is supported with ODF version "n" and "n-1" only.

Hi,
Pointing out to https://bugzilla.redhat.com/show_bug.cgi?id=2152260#c4 once again.

If OCP n and ODF n-1, then make sure:

1) Make sure running below command returns "/compatibility/" (forward slash):
"oc get consoleplugins.console.openshift.io/odf-console -o=jsonpath='{.spec.service.basePath}'"

   a) if not, run following command:
      "oc patch consoleplugins.console.openshift.io/odf-console -p '{"spec": {"service": {"basePath": "/compatibility/"}}}' --type merge"

Repeat step 2) and 3)


in your case n = 11


notice "basePath" field of the command. If OCP/ODF both the same version "basePath": "/" else "basePath": "/compatibility/".

reducing the severity based on response I am getting over this open BZ...
