What do I do when EXCEEDED_MAXIMUM_ALLOWED_AUTHTOKENS appears in form integration?

I am connecting my forms to Zoho CRM via the integration feature you provide but suddenly I receive this error message:EXCEEDED_MAXIMUM_ALLOWED_AUTHTOKENS - what does it mean and where to I fix the issue?

Please, check this link from Zoho where is explained how you can resolve  this on your Zoho account: https://forums.zoho.com/topic/exceeded-maximum-allowed-authtokens 

Here's also another link that will help you to get more info about authentication token and how to generate a new one: https://www.zoho.com/crm/help/api/using-authentication-token.html
