We have an application that we're rolling out to a few hundred Open Dental practices. We recently rolled out to a practice where we routinely get an error from Open Dental when attempting to use the POST query API. The error is about connecting to our SFTP server. The error is only occurring intermittently though. We will go through times where things are working normally and times where nothing is getting through.
This is the error message:
We have close to 30 OD practices online so far and are not having this same issue with any other practices. All are successfully using this SFTP server to save the results of POST requests very reliably. When we logged into the machine to do some direct testing we were also able to make a successful SFTP connection using Filezilla.Unable to save query result. Connecting to [address] has failed with user: [username]\\r\\nA connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond\"\nInner Exception: Response status code does not indicate success: 400 (Bad Request).
What are some good steps to take to further troubleshoot this issue? Are there logs we can look at or settings we can change to try and address this problem?
Thanks!
