Main WP Child Disconnecting Random Sites Daily 62/22/2024

The past 3 days I have been experiencing a recurring issue - Several sites in the Main WP Dashboard disconnected. I went to each wordpress site, deactivated the WP Child Plugin and re-activated it then returned to the Main WP Dashboard and reconnected them. All worked fine except this is now a reoccurring issue. Every day several sites disconnect and have to repeat the same process to reconnect. Is this a new issue? I have not been able to find any recent articles on this. Please advise

Hey @tech7000

Welcome to the MainWP community.

a)
Can you try reconnecting these sites from the Dashboard without re-activating the Child plugin?
If you cannot, what error message do you get?

b)
Are these sites disconnecting when you are performing some Dashboard tasks, such as syncing or updates?

c)
Can you please post the community system report from your MainWP Dashboard for review? The report is located in your Dashboard under Info → Server, on the top right of the page.

A) I tried that the first few times. generic error message telling me that the public key is already set, try deactivating and reactivating the mainwp child plugin

Enter

B) No, no task is being performed

Thanks for the update.

Could you temporarily deactivate all plugins on one of the affected Child Sites and then try reconnecting the site via the MainWP Dashboard?

This would help us eliminate any potential conflicts or security plugins that could possibly be blocking the connection.

If that doesn’t help, please open a private Help Desk ticket so we can collect some additional information & investigate further.

And please refer to this Managers thread by its URL in the ticket.

I’ve started to see this too with random child sites. Had one this morning and I got an email with the following error, which may help:

Hey @dsbking, thanks for sharing the error log.

The team is looking into this and I will update this thread as soon we know more information.

The development team has prepared a pre-release version of the MainWP Child plugin that should help prevent future disconnections of this type.

If you wish, I can send you a pre-release version via a private message.

Perfect, Yes I would like to try the updated plugin.

I have just sent you the pre-release version.

Let us know if you experience random disconnects again, and we will take a closer look.

Keep in mind that random disconnects can happen for various reasons, but we’re hopeful that this change will eliminate disconnects of this kind.
