Jira loads a blank page after logging in

[raoweiheng]

The jira service will display a blank page after logging in every day recently, and the configuration has not been changed recently, and the log content is not very helpful. It will return to normal after each restart. Ask for help! ! ! Operating system: CentOS release 6.5 jira version: v7.3.6 At 9:32 on March 24, there is a prompt for a wrong password, and a blank page will be displayed after the password is correct. The following picture shows the login screenshot:

Hi @raoweiheng

can you rule out any App is causing this? Be sure to spot any outdated/incompatible Apps.
Probably clearing the plugin cache (according to: https://jira.atlassian.com/browse/JRASERVER-27314) could help should it turn out an App is involved.

If you feel an App is contributing to the blank page putting Jira into safe mode (through UPM) could be an idea - just make sure you test this outside office hours to not disturb users.

Also your Jira version seems a bit dated. Probably an upgrade to a recent version could contribute and have a positive effect.

Regards,
Daniel

Hi @raoweiheng , I think it is some problem of your browser. I found this thread (https://stackoverflow.com/questions/29894154/chrome-neterr-incomplete-chunked-encoding-error). Could you check your antivirus software?

The server is a linux system. When the problem occurs, I try to access multiple computers and different browsers, but the problem still exists. The "net::ERR_INCOMPLETE_CHUNKED_ENCODING 200" in the above figure is an error reported after jira is closed, otherwise the resource is always loaded. Screen
