Hey, @JamesBond777👋 Troubleshooting these can be a bit tricky. And I am happy to help where I can. Can you please DM me the email address you are using? This is typically our best place to start troubleshooting.
My other suggestion is, if this is a paid portal with access to support, to file a support ticket solely for the login issue. They might not be able to help with anything on the Syscloud-side of things, meaning the integration itself. But the may have more insight than I am able to glean.
And if the issue resolved itself or was resolved, please let me know.
