Error connecting to sync server: received HTTP/0.9 when not allowed

Hi CSPro users,

Im getting an error:

Error connecting to sync server: received HTTP/0.9 when not allowed

When im downloading data from a csweb server, I dont know the cause for this error. Actually I was downloading it before, I dont know what went wrong.
Help please...

Thanks

HTTP/0.9 is an old protocol developed in 1991. By default cURL disables the handling of this HTTP version. You could turn it on:
https://everything.curl.dev/http/versions

The better question might be to ask why the server is sending HTTP/0.9 requests (if it actually is)? I would have your server team look into this.

Please help me also, this message keep on reappearing every time I download data from Dropbox: "Error connecting to sync server. failed sending HTTP POST request"

Thank you in advance.

Hello,

It seems you are having an error connecting to the sync server for different reasons. Please attach (or send to cspro@lists.census.gov if it contains sensitive information) your sync.log file, found in desktop CSPro at "Help -> Troubleshooting -> sync.log file" or in your CSEntry folder on mobile. This should contain details about the post request and why it failed.

Hope this helps,
Justin
