A Socket Hangup means that the server hosting the RSS feed is closing the connection when Nosto tries to access it.

Nosto has implemented a system to only disable problematic terms when the socket hangup issue occurs 12 times within a 14-hour time window. After the 14-hour window, the failure counter will be reset. The reason for this is that some RSS terms have a very long polling frequency (e.g. once every 1 hour). After 12 re-tries this strongly suggests that the term is broken.

It is recommended you ensure that your servers and/or security software aren't blocking the connection attempts from Nosto. If they are blocking Nosto, then they will need to whitelist or allow the user-agent 'Stackla'. Once this has been done, the servers should stop closing the connection from Nosto's attempts.

Additionally, the disabled terms will need to be reactivated so that new content can aggregate in your system. To re-activate these Terms please go to Discover > Terms and click on Edit to open the RSS feed that had connection issues. Once open, go to the Active tab and select Activate Term. Click Save to complete the process.
