We have started to experience the same issue in our office. 4 of our sites have randomly disconnected today. They were running multiple versions of the software on the child plugins. I updated each of them to 4.5.0.1 after the issue began to see if it would resolve the issue but it did not. When trying to reconnect them, I need to deactivate and reactivate the child plugin. They will then reconnect, but when I go to sync data, they disconnect and I see an error “HTTP error - HTTP/2 send again with decreased length”.
These sites are on two separate servers. One server is running litespeed and the other is running nginx.
I have only been utilizing the platform for about 6 months so the 2018 version would not be applicable to me.
Your issue may be unrelated to the original problem from this topic, so we’ve created a new one.

Thanks for the system report. Nothing in it stands out as an obvious issue.
Can you please set your Action Logs to Debug and then try to reproduce the same “HTTP error - HTTP/2 send again with decreased length” error?
Perhaps the Action Logs will catch some additional information.
It looks like my action log was already set to debug. There is a whole bunch of stuff there from September 13th, but nothing since.
Once the site has disconnected, I try to reconnect but get an error “Public Key already set. Please deactivate and reactivate child plugin and try again”. Then I deactivate and reactivate the child plugin and the site will reconnect without issue. When I try to sync the data for my sites, I get red exclamation marks on 4 out of 186 of my sites and the sites become disconnected. When I hover over the red excalmation mark, I see the message “HTTP error - HTTP/2 send again with decreased length”. I will attach a screenshot.
This just began today. 3 of the 4 sites that are having the issue are on a WPO plan with Bigscoots. They are the only sites that we have on that server. I reached out to Big
scoots today and provided the server logs, but they could not identify the issue and suggested I reach out here. The 4th site is on a shared server where all of our remaining sites are located.
Thanks for the additional information.
Would you mind opening a private Help Desk ticket so the development team can collect some additional information & investigate further?
And please refer to this Managers thread by its URL in the ticket.

This issue has been resolved. MainWP Support provided a beta version of the dashboard software that corrected the issue.
