Cannot use Basic Search - "The Jira server could not be contacted..."

[SRBR SE]

When users try to search by Basic search mode, Jira shows the following message:

"The Jira server could not be contacted. This may be a temporary glitch or the server may be down."

But Advanced search with JQL does not shows this error

It happens if I try to fill any field by Basic search. It not allows to select any option defined at Basic search

same experience here, not using IIS, only from hosts outside the environment hosting the application

Same problem here with JIRA 8.13 and 9.4. Suddenly started occuring. Already investigating it with atlassian. What is interesting seems that not all users have it but all from our company..

[Krzysztof Bartosiewicz]

On our side it was due to new security signatures on our firewall...

[Edward Smith]

interesting, ooc can you divulge what firewall you use? (Palo/cisco/sophos/etc.)
