Hello MJ,
Thank you for your message.
Could you please clarify if you have also changed the port in the
Server manager on the
Manage tab in the
Viewer?
![Custom Security Server - 30 Aug 2019 01:42:10](/bitrix/components/bitrix/forum.interface/show_file.php?fid=5442)
If not, please try changing the port, as the information about the port for signing in to the server is taken from the Server manager window.
Please let me know if the issue persists.
