Hi Team,
We are using EO.Pdf -Version 6.0.29 (licenced) in one of our applications,
It was working fine with http.
Recently we have upgraded our application to HTTPS, from then it stopped working and
below are the various error messages encountered as we tried to make it work in different ways.
We also tried by upgrading the tool to Version 19.1.25 (trial), but we are not successful
1. (404:The server has not found anything matching the requested URI (Uniform Resource Identifier).
This is an error returned by the Web server, not by the HTML to PDF converter.
Please try to visit the same Url with your browser to verify whether the Url is valid.)
When we checked the URL in browser, it is OK, we are able to see the response in browser.
2. The remote server returned an error: (401) Unauthorized.
When: UseDefaultCredentials is set to true;
3. Error code:-375
When hardcoded credentials are sent
Let us know if you need any more information.
Regards,
Sravan

Hi, You definitely want to start with the current version since your version is very old and we no longer officially support your version. As to other issues you mentioned: 1. 404 error. This is an error issued by your web server that is not directly related to authentication. So you can only find out why you are getting this error through your web server. If necessary, you can use a traffic monitor to monitor the traffic exchanges between the converter and your server and that is often very helpful in find out the root cause; 2. UseDefaultCredentials. We do not have such property. So we won't be able to provide you any information on this; 3. -375. This error is TOO_MANY_RETRIES. See here for the complete error codes: https://cs.chromium.org/chromium/src/net/base/net_error_list.hObviously this points back to the authentication error. Hope this helps. Thanks!

Hi Team,
Thanks for your reply. Let me put the problem statement around -375 error.
The issue occurs at Pre-prod server and F5 load balancer handles the traffic between 2 web servers. I have tried using EO.pdf 's convertUrl feature with proper domain name, user name and password. It gave -375 error. I have used EO.pdf version 19.1.25.
While the same setup on Qualif server without F5 load balancer and 1 Web server, it worked fine without any problem.
Please help us to address the issues.
Hope, this context helps you to find root cause.
Regards!

Hi,
This is something you should work out with the load balancer. A load balancer supposes to be transparent to upper layers and EO.Pdf does not have any code that particular works with a certain type of load balancer, so it's not something we can fix on our end. So you definitely need to focus on the load balancer itself to find out why it broke a normal authentication flow.
Thanks
