Hi @harvis
I hope you’re well today!
I’m not aware of any known bugs/issues with this integration and I don’t see anything currently reported in our internal bug tracking system.
I also just tested it with our test instance of Sendy and my personal test site (just default WordPress with Twenty Twenty One theme and Hustle plugin) and I could configure it without any issues.
The error that you are getting also doesn’t suggest invalid credentials but rather come sort of either connection issue or some internal conflict/resource issue.
I understand that due to the issue you’d rather not test it anymore on the live site but do you have (or could you have) some staging/dev site where you could try safely set such integration again from scratch?
If yes, please give it a try but also
1) first enable WordPress debugging by adding following lines to the “wp-config.php” file, right above the “/* That’s all, stop editing */” line:
define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );
2) make sure that the IP of where your Sendy instance is installed is not blocked by any firewall/security tools and, vice versa, that at the other end (where you Sendy instance is installed) the IP of your site is not blocked/filtered in any way
3. then try setting up the integration but keep browser console open during the process and look if there are any errors showing up in it
4. and then (if it fails again) look for the file named “debug.log” in the /wp-content/ folder of your WordPress installation.
This file should contain some entries that may be additional errors or warnings related to Hustle and/or communication with Sendy installation so knowing about them could help diagnosing the issue.
Kind regards,
Adam
