I am unable to access the application without a client. I have Integrated Okta for reverse proxy. Whenever I try to access the application, I am getting an error: 500 : Netskope was unable to process authentication request for tenant:<18507>. couldn't create AUTH URL: runtime error: invalid memory address or nil pointer dereference.
When you say you integrated Okta for reverse proxy, what app did you select? This error likely requires some additional investigation by our support. I'd suggest opening a case with a HAR capture and your tenant details.
