I am having issues with LibreNMS Web GUI yet validate is showing that everything is correct

FYI, validate only checks some possible problems. No way to detect all possible problems.

DId you check you librenms.log file and web server logs for errors?

I can see the following error in the nginx logs

I am now at a loss what to do next! ?

Any ideas would be appreciated!

Bizarre, not sure how you caused that.

Try deleting the vendor directory and running ./scripts/composer_wrapper.php install --no-dev to re-install them.

Hi

Weirdly everything is working again this morning - without doing anything!

I saw this reply late yesterday and decided that i would try Murrants recommendations first thing this morning!

Before starting I decided to connect via the Web GUI, just out of interest and its working!

However, I have found the following from .validate.php

There is nothing in the Nginx error log (its empty) - so this problem appears to have resolved itself. There error log from yesterday was updating throughout the day.

Bit unsure where to go next? Other community posts where “poller method” and “python wrapper” are failing don’t seem to be the seem to the same MO.
