Dispatcher Service not updating LibreNMS

Help
1

Hello,

I can run daily.sh manually and LibreNMS will update, however the Dispatcher Service is not updating it automatically.

Checking the daily.log, I see the following errors:
In Request.php line 322: Invalid URI: A URI cannot contain CR/LF/TAB characters.

Here is the output from validate.php:

Any assistance is appreciated!

Just for verification, I ran daily.sh today and it was successful:

Ran validate.php and issues with RRD:

In RrdProcess.php line 74:

Restoring from backup for now.

Any advice appreciated!
