"The connection to the server failed. Please try again!"

[Tom Lahey]

Blog2Social was working until this morning. Now I get "The connection to the server failed. Please try again!"

I have tried turning off all other plugins except Blog2Social and am still getting the error.

There is no Cloudflare type server for the site.

I get this when I try to schedule through the calendar, I click "Add A Post", then "Share your WordPress posts, pages or products", and the error message is shown.
However, I can schedule it through the "All Posts" option.

Does anyone have insight?

Thanks!

Hello,
it seems that something is blocking outgoing connections. Did you install Wordfence or another security plugin?
Please try to solve the following issues:

I have tried turning off all security plugins. In the end, I cloned my site, turned off ALL plugins except Cloud2Social, and disabled all server side caching. (Cloudflare, Breeze, and Varnish).
I have whitelisted the Cloud2Social IPs and my server IP's in my hosting company's firewall.

The only part of the plugin that seems to be impacted is creating a new entry in the Calendar function, I can edit existing entries and create listings in other ways, just not through the Calendar function.

I host with Cloudways.com, is there any known issue with Cloudways hosting and Cloud2Social?
How can I determine if the issue is the noted 504 Error due to DNS entries?

Thanks!

Hello Tom,

Thanks for your reply.

Please be aware that this notification is likely caused in your individual WordPress environment by
- a slow server and results in a server-side timeout of your website
- too strict security settings (for example, Cloudflare, Wordfence or other security plugins, firewalls or your host)

I recommend checking the steps in this guide to solve the issue, as simply deactivating certain plugins may not resolve it if their settings remain active:
The connection to the server failed. Please try again!

Best regards
