Optimize connection buffer size

I'm trying to run the command wp csp generate and it starts to work but then I get a pop-up stating that if the issue persists, turn off the "optimize connection buffer size". It took a long time to find it but I did under advanced of the site connection and disabled it.

However, the same issue and message persist. If I allow it to retry on it's own — I'll get the error:

There was an error gathering the resources: Invalid post ID

which I cannot find any information on regarding WinSCP.

Does anyone know how to correct this error I'm getting because it's not listed in the error section of the documentation?

Please attach a full session log file showing the problem (using the latest version of WinSCP).

Actually, the error is "Invalid File ID" I did turn off the "Optimize Connection Buffer Size" as suggested but the error persists. I also reached out to my host to see if they were blocking it and they ran the same command wp csp generate and received the same error. They wondered if the command is valid, though it appears to initialy accept it.

Here's the log.

So it is not a WinSCP problem, right? Or does the command work in a regular SSH terminal (such as PuTTY)?

I tried to do it manually and got most of it but there were some sticking points. At this point, I don't have the time anymore to keep messing with this. For the first time ever in 16 years running my podcast and website, I'll have to hire a developer.

What's really sad about the CSP is that it's not a silver bullet for security. In fact, not even close but Google now adds it to their best practices and will likely soon be mandatory. Really annoying.

Thanks
