Issue search causes “JIRA server could not be contacted, this may be a temporary failure..."

[Jason Saunders]

I have got an error window stating "This may be a temporary glitch or the server may be down." when I do an issue search. To be clear, this is the search from the "Issues" dropdown menu in the main navigation. Then check a project from the "Projects: All"  dropdown and click the "Update" button. As far as we know, nothing has changed in the environment.

For us Palo Alto was blocking requests for 'QueryComponent!Default.jspa'.

https://jira.atlassian.com/browse/JRASERVER-74757

It has been solved by the network team.

I raised on official support ticked and got reference to this topic The JIRA server could not be contacted. This may be a temporary glitch or the server may be down. | Jira | Atlassian Documentation In fact we have a polish language instance and are using Field Security Plugin. Are you also using this plugin and some translations?

Mine has also been doing this for over a week. Thought it was an issue with my work's server updates, but turns out it is a JIRA problem.

We have the same problem both on PROD (8.20.13) and TEST (9.4). Problem also with changing type when searching in basic mode. The difference is that in 8.20.13 we get the message after choosing project/type immediately and on 9.4 the error shows after clicking search.. Any ideas?

Were you able to figure out where the problem originates from? We have the same error

We see the same error. Was there on Jira 8.22.6 and also now on 9.4.2.

Search for issue (Basic Search). Searching for a project. When clicking one of the 
drop down project the error message pops up.
