Some Service Desk Tickets Cannot be Viewed Through Customer Portal

[Wansze Kong]

After our recent upgrade to Jira Server 8.5.3 and Service Desk 4.5.3, several of my clients are unable to access their Service Desk tickets via the Customer Portal.  This issue seems to be intermittent as it does not occur with every ticket.  Through the chrome console, one of my users was able to capture the following error:

ERR_INCOMPLETE_CHUNKED_ENCODING

Any assistance you can provide will be much appreciated.

Thank you,

Additionally, I was able to acquire the following errors through the site:
