We’ve implemented a couple of fixes to the dynamic DNS as follows:

• SSL errors – we’ve swapped out the SSL cert (some clients were not recognizing the intermediate CA, examples: ddclient) and upgraded it to a geotrust cert.
• Some wildcard requests were not recognized as such: FIXED

Some of the effects of the latter were experienced as follows:

• Synology ddns update FIXED
• Invalid Hostname error FIXED
• wildcard DNS wasn’t being updated FIXED
