Hi,
I have a problem with several VMs on different AZUR tenants.

Some sites display an error: PR_CONNECT_RESET_ERROR in Firefox.
The same works fine from other computer which are not in azure.

Example: https://plex.justice.gouv.fr/zephyr/connect

Can you help me in solving this problem?

    Hi @Kelvyn LEGRAS ,

    Thank you for reaching out to the Microsoft Q&A platform. Happy to answer your question.

    The PR_CONNECT_RESET_ERROR issue is encountered when the user tries to use Mozilla Firefox to connect to a website server with the HTTPS protocol, but the request gets denied. This error message essentially means that the peer or some middlebox in between (most likely a firewall) or antivirus application is terminating the connection forcibly.
    This issue is not azure specific, and it can happen with any machine having such configurations.

    I am adding some third party knowledge base articles here for your help. Please refer to:
    https://support.mozilla.org/en-US/questions/1280856
    https://windowsreport.com/pr-connect-reset-error/
    https://kinsta.com/knowledgebase/pr_connect_reset_error/

    If the issue persists, I suggest you raise a technical support ticket with azure network technical support team for a deeper investigation. If you don't have the ability to open a technical support ticket, please let me know I can help you further on this.
