Simple redirect I'm getting a 405 error

[SteveD1979]

Hi, I'm having an issue but I'm not sure if its with the F5 VIP or the application.  We have a URL pointed at a VIP something.domain.com that has a client side SSL profile tied to it and just doing a simple redirect with no pool members.  This is meant as a log drain from an external vendor and is configured to come in on port 443

when HTTP_REQUEST {
HTTP::redirect "https://splunk server:port/static/log/URI"
}

When we hit it in a browser we get a 404 which is expected but in Postman Posts and Gets return a 405 error.  Is this because the server i'm redirecting to just has a self signed cert and not the same certificate that is configured in the VIP's SSL profile?

@SteveD1979 If you didn't modify the defaults on the F5 when it comes to redirects you can open developer tools in a browser and have a look at the server field for the 405 response, if it's the F5 it will say something along the lines of BIG-IP and if it's something else it wont. You can also perform a tcpdump to see exactly where the 405 is coming from.

Thanks the server listed in under the event in dev tools is the splunk server.  But if he posts right to the URL i'm redirecting to he gets a successful response.

It's advisable to check the SSL certificate on the destination server, ensure proper HTTPS configuration, and review Postman's SSL/TLS requirements.

Can you paste the configuration of the VS here?
i think its a problem with the profile SSL or directly with the postman post/get compile

Best Regard
