For IT Managers and IT Providers: Please also see the Network Requirements section in Installation Guide (for IT Professionals) for domains that may need to allow list in your firewall configuration.

If when logging in, resetting your password or managing your practice account you see an error message like the following:

HTTP/1.1 500 Connection reset by peer
An error occurred while handling your request
SOPHOS
UTM Web Protection

it is likely because your computer is not being allowed to access the Chain website by a firewall on your network.

To resolve this, please could you send this article and a screenshot to your IT Manager or IT Provider and ask them to configure the firewall so that it does not block our website.
