Disconnect and reconnect message

Hello,

I just migrated my website to another hosting and updated the plugin to the latest version, now I get the following message:

“Attention! There may be a problem with your connection to Square. To continue accepting payments, please disconnect and reconnect your site.”

I have disconnected and reconnected, entering my Square credentials and still get the same message. Before migrating and upgrading there was no message.

I Hope you can you help me, thank you.
