There can be many reason why the integration connection got stuck. Some of them are:
Link in not valid: Connection might got stuck if the connected source link is no more valid. In this case, no new content will be created unless you edit the connection with the new source link
Too many pull request: Another reason of connection getting stuck is way too many request from the source link. Please restart the connection in this case and everything will be working again
Invalid data: Another reason for the stuck connection is invalid data which our system could not parse from the source link. Please restart the connection in this case and everything will be working again. Please ensure, that the source of your content only provides data, that the tchop parser can load.
In case you feel that your connection is getting stuck due to some other reason, please write to us at firstname.lastname@example.org and we will look into that for you
