Hi, I receiving the following error intermittently: The plug-in execution failed because no Sandbox Hosts are currently available. Please check that you have a Sandbox server configured and that it is running.
We had our plugins registered in Sandbox mode. Plugin runs on production instance
We used Microsoft Dynamics 365 2020 release wave 1 enabled. Version 1710 (9.1.0.22231) online
Anyone else having problems at present?

It doesn't necessarly requires a ticket to Microsoft Support. Most of the time this error raises due an error in plugin source code. Check this documentation for some samples of error in source code which can cause this error: Troubleshoot Dataverse plug-ins - Power Apps | Microsoft Learn

Hello Alice,

If you keep getting this error you should get in touch with Microsoft Support and open the ticket because this issue is not something you can take care of by yourself.
