Bridge Assets Never Download and only Time-Out, No Firewall Blockage

I’ve been attempting to download Quixel assets through the integrated Bridge plugin (Unreal 5.3.2), but have been unable to download anything other than MetaHumans assets. I have worked with my corporate IT team to whitelist any domains or IP addresses necessary, having already solved issues with user authentication and domain communication. However, having solved all of these other issues, attempting to download any non-MetaHuman asset simply sits until the download times out. Looking at the log, the only obvious error message that keeps reporting is the following:

“{“date”:“Mon Mar 04 2024 14:01:11 GMT-0500 (Eastern Standard Time)”,“error”:{},“exception”:true,“level”:“error”,“message”:“uncaughtException: Cannot read property ‘resolve’ of null\nTypeError: Cannot read property ‘resolve’ of null\n at b.a (C:\snapshot\node-bifrost\node_modules\node-downloader-helper\dist\index.js:1:6259)\n at Timeout._onTimeout (C:\snapshot\node-bifrost\node_modules\node-downloader-helper\dist\index.js:1:10801)\n at listOnTimeout (internal/timers.js:557:17)\n at processTimers (internal/timers.js:500:7)”,“os”:{“loadavg”:[0,0,0],“uptime”:303929},“process”:{“argv”:[“C:\Program Files\Epic Games\UE_5.3\Engine\Plugins\Bridge\ThirdParty\Win\node-bifrost.exe”,“C:\snapshot\node-bifrost\packages\bifrost-server\dist\index.js”,”(null)“],“cwd”:“C:\Program Files\Epic Games\UE_5.3\Engine\Binaries\Win64”,“execPath”:“C:\Program Files\Epic Games\UE_5.3\Engine\Plugins\Bridge\ThirdParty\Win\node-bifrost.exe”,“gid”:null,“memoryUsage”:{“arrayBuffers”:2897313,“external”:4596391,“heapTotal”:23744512,“heapUsed”:19798928,“rss”:64360448},“pid”:19836,“uid”:null,“version”:“v14.20.0”},“stack”:“TypeError: Cannot read property ‘resolve’ of null\n at b.a (C:\snapshot\node-bifrost\node_modules\node-downloader-helper\dist\index.js:1:6259)\n at Timeout._onTimeout (C:\snapshot\node-bifrost\node_modules\node-downloader-helper\dist\index.js:1:10801)\n at listOnTimeout (internal/timers.js:557:17)\n at processTimers (internal/timers.js:500:7)”,“timestamp”:“2024-03-04T19:01:12.032Z”,“trace”:[{“column”:6259,“file”:“C:\snapshot\node-bifrost\node_modules\node-downloader-helper\dist\index.js”,“function”:“b.a”,“line”:1,“method”:“a”,“native”:false},{“column”:10801,“file”:“C:\snapshot\node-bifrost\node_modules\node-downloader-helper\dist\index.js”,“function”:“Timeout._onTimeout”,“line”:1,“method”:”_onTimeout",“native”:false},{“column”:17,“file”:“internal/timers.js”,“function”:“listOnTimeout”,“line”:557,“method”:null,“native”:false},{“column”:7,“file”:“internal/timers.js”,“function”:“processTimers”,“line”:500,“method”:null,“native”:false}]}

Without knowing the reason for this error, I can’t very well help my IT department solve any issues that might be stemming from group or user policies. Can anyone tell me what the core problem is that would be causing this issue and error message?
