Blank page after logging out

snghoshi commented 2 years ago

Since upgrading to version 4.2.x and now at 4.3.1. My Graylog server works find until i logout then the browser just display a blank page. The only way to login via the browser is to restart the graylog service again then it will work (display the page) until i log out. Running on Ubuntu.

Hey @snghoshi,

do you see anything in your browser's JS console when you try to login/seeing the blank page?

Hey @snghoshi,

thanks for getting back to me. Can you do the following and post the output?

curl -v https://10.10.x.x/config.js

(Please replace the ip with the one of your Graylog server)

snghoshi commented 2 years ago

Hi @dennisoelkers , thanks for your reply. Please find requested info below (please note i masked the IP details):

Can you try it like this (with an additional -k)?

curl -kv https://10.10.x.x/config.js

Okay, that looks good. I am suspecting the telegram notification plugin to be the culprit, as it is probably outdated. Can you try removing the plugin and see if it still happens?

snghoshi commented 2 years ago

Hi @dennisoelkers , Thanks. i have renewed the TLS cert.

Im getting the following: There are 2 notifications

Notifications are triggered by Graylog and indicate a situation you should act upon. Many notification types will also provide a link to the Graylog documentation if you need more information or assistance. Failed to send Telegram messages. (triggered 3 days ago) API request failed: api.telegram.org: Temporary failure in name resolution (java.net.UnknownHostException: api.telegram.org: Temporary failure in name resolution) You are running an outdated Graylog version. (triggered 4 days ago) The most recent stable Graylog version is 4.3.2 (Noir) released at 2022-06-15T00:00:00.000Z. Get it from https://www.graylog.org/.

I would like to upgrade to version 4.3.2 and then i will look at the Telegram notification plugin. I will revert back with the results.

snghoshi commented 2 years ago

Hi @dennisoelkers , thanks a lot for your help.

I upgraded to version 4.3.2 and also the Telegram notification api to version 2.3.9 and now it seems all is fine again.

Appreciated.
