    Hello Kanagaraj,

    Can you please check if correct reverse proxy setting is configured in Apache’s config file (httpd.conf)?

    Reverse proxy setting for reference:

    <VirtualHost *:80>
      ServerName <hostname>
      ProxyPreserveHost On
      ProxyPass /openspecimen ajp://localhost:8009/openspecimen
      ProxyPassReverse /openspecimen ajp://localhost:8009/openspecimen
    </VirtualHost>
    

    If you are using the HTTP port instead of AJP then change the protocol name (ajp -> http) and port (8009 -> 8080) in above configuration.

    Thanks,
    Krishna

    Hello Kanagraraj,

    In those shared files no error is displayed. Can you provide me more details?

    1. Was the OpenSpecimen instance up and running before? Has anything changed recently like server IP?

    2. Share the Apache’s error log file.

    3. Try accessing OpenSpecimen using “http://10.100.1.47:8080/openspecimen” URL and see if OpenSpecimen is accessible.

    4. If #3 does not work, then share the os.log file present at $os_data_dir/logs/os.log location.

    Let me know what OpenSpecimen version are you using.

    Thanks,
    Krishna
