Hello, I am not sure if anyone else is having this issue, but when I try to update Community Builder, I get the following error:

TypeError: Failed to fetch

After the "failed" attempt to updpate, it appears as if the update actually took. Very strange. Idealy, it should say the update was completed successfully since the update notice is gone after the failed attempt. I have even tried reinstalling Community Builder but I get the same error, even though the installation appeared to be successfull.

My server stats:
Webserver nginx
Joomla version 4.1.2
php version 8.0.18 (socket based php-fpm)

Any help would be greatly appreciated.
Thank you.

I tried using Install from web from community builder, as well as a standard extension install from Joomla where you have to upload the package to the server.

I know that CB uses it's own plugin to check for updates. That is what shows when initially logging in to the back end where it informs you that there is an update. It has the "Update All" button, and only shows CB updates (separate from other Joomla updates).

Joomla's install from web does not seem to show the CB updates, while it does show updates for other components, modules, or plugins.

To reproduce the issue, I just have to wait for a new update to CB. Then I login to the backend, and at the top of the page in red it says something about a new version of CB. Click on that, it takes you to CB install from web. Click update all, and it start the update, but the status says the updated failed with that error. Afterwards, there is no more update notification for CB until the next version.

I also tried to download the latest package from joomlapolis. From there I went to Joomla's install extension and uploaded the package. Same thing happens. It appears to have installed, even though the package installer reported it as a failed install.

I have checked the database for errors and found none. All tables are up to date. Allow origins is set to the default as well, an asterisk. It should match without an issue.

Thank you about checking on the installer behavior. I actually took screenshots of the entire process today. Here is the installation details:
