ColdFusion Server 2021 - 500 - Internal server error.

[ColdFusion_User]

Hello Community,

I have inheritted some ColdFusion servers (2021). That has been running great so far but recently, I encountered an odd issue with one of the servers. The issue is that the server stopped processing requests on all instances, whether from websites, APIs, etc. I have tried a number of actions to get this server to start processing requests but all actions have been proven futile at this point.

Steps I've taken:

1.  rebooting the server
2. resetting the IIS (restart all coldfusion services)
3.  recreate the IIS connectors (restart all coldfusion services)
4.  Ensure all services are running
5.  Upgrading to the latest available patch (22) on all instances
6.  Tried creating a new cluster and instance
7.  I've given elevated permission to the IIS user (IUSR) for all sites
8.  Verified certs
9.  Verified Handler mappings
10.  I checked all possible logs (server, application, exception, etc) but can't find anything that would indicate the error.
11.  Check event manager logs for System and Application but don't seem to find anything that jumped oput
12.  I followed some extensive process I found using AI but still nothing.

I can't seem to open a case with adobe as I am getting the error below and the admin is no longer available.

 

What I haven't done so far is to re-intsall the IIS Roles and Features. If anyone has experienced and have a solution or can help in anyway, please reach out. Thank you

I'm sorry to hear of your challenges. First you have not shown what the error is. Your screenshots show that Cf itself is working, which is a great start. I suspect it's something in your iis configuration. The error message may help us, but perhaps not. 

I'll say as well that I am confident I could have your server back up (cf site serving requests again) today, perhaps in as little as 15 minutes, via remote screenshare consulting. For more on my rates, approach, satisfaction guarantee, online calendar, email, phone, and more, see the consulting page at carehart.org. I have open slots now and into this evening. I can also help after what's offered on the calendar. 

Hope we get you back on your feet ASAP, one way or the other.
