Hey Bhupendra,
It appears that the License Transfer feature on my.kepware.com is broken due to a CORS issue that your website is experiencing.
There is also another error message that the FileReader.readAsDataURL() is also improperly implemented. Error message is: "Failed to execute 'readAsDataURL' on 'FileReader': The object is already busy reading Blobs". This means you guys are most likely using a single instance FileReader instead of one per request.
I also find it disappointing and not particularly customer-friendly that Iām being asked to purchase a support contract to address a problem that stems from a malfunction on your own self-service website. The fault lies with the broken web features, not with the customer trying to use it.
Best wishes
