Hi, tonight our website shows "Invalid Response From UPS Server" and no UPS rates in the shipping estimator; the USPS integration still works normally.
Can anyone suggest our steps to troubleshoot this right away?
Unfortunately I'm working away from the office for the next 48 hours and can't upload any includes.php debug parameters until I return. Any suggestions to troubleshoot without FTP access will be greatly appreciated.
Andy, it looks like the issue, which impacted multiple ECT customers at our webhost, was caused by Linux environment update libcurl.x86_64 0:7.29.0-46.el7 and seems to be resolved now.
