Jira Connector Sync Issues / JIRA Authentication

Options

Can anyone help. Last Tuesday my JIRA Connector just stopped working. I am getting hundreds of errors occurred during sync notifications for all my workflows. No settings had been changed, this just suddenly happened. Everything had worked perfectly before.

I think it might be a JIRA authentication issue but I cannot for the life of me figure out how to change things to get this to work again. I am getting errors like

Invalid response from JIRA. statusCode: 401, reasonPhrase: Unauthorized

And it keeps telling me to configure JIRA which I have done again and again but it doesn't work anymore. I have tried to update the Application Link in JIRA with details provided in an article on configuration but that didn't help. I have checked the webhooks and they look fine.

JIRA support have advised me to use an API token but I can't see where to put that within Smartsheet and Smartsheet support have ignored me for 5 days now. I have a number of projects suffering because this has just stopped working.
