3 sites disconnected randomly

Today, 3 child sites disconnected with no apparent reason. They are on different hostings, without cloudflare or specific firewalls.

All the sites are online and fine.

I have tried to reestablish the connection but to no avail. Also, I have deleted one website from the dashboard and tried to re-connect it, but I get this error:

Error message: SSL certificate problem: unable to get local issuer certificate

I have run a check and the certificates are fine…

How can I fix this? Thanks

That suggests that the SSL certificate is incorrect or incomplete, so please check the certificate with a tool like SSL Checker
After fixing that, it should hopefully work again.

While typing this you’ve edited your post, but we can’t check it because you don’t mention the domain. Did anything else change for these sites on hosting level or DNS?

Thanks for your quick reply!

I have checked the SSL with the tool, but it is fine.

Also, the 3 websites that got disconnected are on different hostings. I suspect something happened with MainWP (even if I didn’t change anything).

The site is https://agenziagreen.it/
Another website is: https://www.assoplmilano.it/

Your child site agenziagreen.it appears to be using Cloudflare.
The SSL certificate problem you get can indeed occasionally be caused by CF.

Can you reach out to the hosting support and see if they can whitelist your MainWP Dashboard URL/IP address?

Thanks for your reply!

I’ll try to contact the hosting support. However, this other website: https://www.assoplmilano.it/ doesn’t use Cloudflare and has the same problem. (UPDATE: now the connection with this site has started working again, weird…)

Everything worked fine until today… Isn’t there anything I can do inside Mainwp?

Thanks!

Ok, I have done some more troubleshooting. There is something that is very confusing for me:

while testing connections inside MainWP, the URLs with and without www behaved differently (meaning that one failed and one succeded.) This way, I managed to reconnect www.lettureserali.it/ But, to reconnect it I had to use the URL without the www (even if the original url has it!)

The site https://agenziagreen.it/ tested fine with www (even if it doesn’t have it) and failed without (and I couldn’t connect it anyway)

Ok, last update:

now everything works again. I didn’t do anything, so I guess it was a temporary problem.

It would be nice to understand what caused it.

Thanks!

Glad to hear it’s working now.

It’s hard to say what caused this temporary issue.

I would suggest reaching out to your hosting support and see if they made any Cloudflare or networking changes around that time.
