XF 2.1 tools/run-job - installing/upgrading add-ons errors to 404 page halfway

[jul]

Dear Xenforo Community,

Recently I've been getting quite frustrated with simple tasks as installing and upgrading a wide variety of add-ons.
Whenever I try to install/upgrade any add-on it will redirect it to a 404 error halfway through the run-job. Making it impossible to quickly install or upgrade anything.
For each installation or upgrade I can expect it to error. This means I'll have to spam the rebuild button untill it stops showing the 404 page and proceed to install/upgrade normally. It is very time consuming and frustrating.



Hopefully someone is known to this issue and could help me out.

Thanks for reading!

What does the 404 error say specifically?

This is likely a web server module that attempts to avoid (D)DoS attacks, but is triggering a false positive as the add-on actions refresh the page a number of times. There are potentially logs relating to this in the web server error logs. Ideally, you'd want admin.php to bypass this, at a minimum. Your host can likely help resolve this.
