@shardhak this is the same issue that I'm experiencing.

@sapra5379 can you screenshot the browser logs on Chrome (redact your SFTP URL) by pressing F12 (Developer mode) on the webpage after you login?

Can you share the error from dev console logs?

Hi kshardha, here is the screenshot.

Check your Flask configuration file (backend) and the entries you had for your domain etc in 04a script. Also, check if the certs you are using allow for the FQDN you are configuring for the application.

The flash configuration file and the 04a script contain the same domain/cname configuration. I am using a wildcard cert. *domainname.com

One more thing to check, share the ECS logs for the backend tasks that are running. See if you have encountered any error there.

Try updating the requirement.txt file using the following and rebuild docker image, upload it and re-create the ECS tasks:

Werkzeug==2.0.0
jinja2==3.0.3
Flask==2.1.0
Flask-Cors==3.0.8
Paramiko==2.7.1

Is there any solution to this bug? Currently facing the same issue. In the console window, the error message starts with "Unexpected token '<', "<!DOCTYPE..>" Is there a problem with the response returning an html file?
