Firebox Denying Traffic: HTTPS Invalid Protocol

Firebox T40
Version 12.7.1.B644848

We replaced a failed network device relating to Car Wash equipment. Device is same model # as previous. It's assigned IP: 10.11.17.129. We had no Firewall Policies in place for previous device. However, device is being blocked by Firewall communicating with external server. Receiving the following in Traffic Monitor:

2022-06-08 16:35:08 Deny 10.11.17.129 72.78.XXX.XXX https/tcp 1057 443 Trusted External ProxyDrop: HTTPS invalid protocol (HTTPS-proxy-00) proc_id="https-proxy" rc="594" msg_id="2CFF-0007" proxy_act="Default-HTTPS-Client" length="0"

2022-06-08 16:35:08 Deny 10.11.17.129 72.78.XXX.XXX https/tcp 1057 443 Trusted External HTTPS Request (HTTPS-proxy-00) proc_id="https-proxy" rc="548" msg_id="2CFF-0000" app_id="0" app_cat_id="0" proxy_act="Default-HTTPS-Client" action="drop" sent_bytes="64" rcvd_bytes="0" tls_version="SSL_0" tls_profile="TLS-Client-HTTPS.Standard" sig_vers="18.060"

Please let me know if additional information is needed. Any thoughts or suggestions would be much appreciated.
Thank you!
