Scheduled Tasks Error

Hi,

Since upgrading to Nop 4.2, I'm having issues with scheduled tasks like email sending, currency update, etc. It is giving me a parameter expiration error, as pasted below in full.

Please someone assist.

Seems error is thrown from .net framework. You may find your solution from here.

set Schedule tasks Seconds (run period)  value more than 10second. its work for me.

Hi,

Have done that, and restarted the application, but still no change.

I had lots of problems with this, a few things to check.

Log onto your server and see if you can ping the domain and make sure it returns the correct ipaddress also.

Double check you can also browse your site using external address from your server itself.

I had a plugin that was blocking my own server. When it runs scheduled task its not handled internaly it goes out to the www than back into therver itself.

I hope that makes some sense.

My problems were as follows.

And assuming you are ssl

In settings > store make sure ssl is checked and store url has https not http and strire name is not a web address

then in all settings makesure force ssl is true

After this i found that in Windows host file had an entry to point to an old server deleted these

Then another time i had noip filter (addon) which was blocking spain where my server is located added my server ip to the allow list this was another reason shed tasks stopped

I hope this helps you troubleshoot your issue.🤪
