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.

Good morning Charlie,

Thanks for reaching out. I tried uploading more screenshots but they keep getting discarded, not sure why because there's no sensitve data being captured. Let me try again.

Website Error:

 
CF services:

 
IIS Connectors

In regards to your rates, I will have to consult the business as this is an enterprise level setup and get back to you on that. I also believe it's the IIS but not sure what exactly.

That's still not enough for us to know. It could be either an error in cf or in iis. 

First, go into iis and change the server level "error pages" feature to enable "detailed errors", so that you can see more. (You can revert it later to the default of detail for local, custom for others). 

With that detail, what's the error. We don't HAVE To have screenshot. You can just paste the text. 

Look also in the coldfusion application.log, which tracks a line for each cf error (and the exception.log, which tracks several lines per error). And BEWARE that since you're using multiple instances, each has its own log directory (or it would by default, though some mistakenly change that to have all write to one folder--a terrible idea.) And don't presume to look only in the logs folder of the instance you "see" is mapped to for the site, per that wsconfig screenshot. That's what CF thinks...but someone could have manually tweaked how IIS is configured. 

This may sound daunting or overwhelming, but it's really not...especially for someone who sees it all and helps people assess it daily like I do. 

I've tried to give you enough detail here that you MAY be able to solve things with the above alone. Some need more detail, others might find info that needs MORE explanation. We won't know what's amiss until you report back. 

I'm guessing this not production, or your folks wouldn't be making you wait to get help. Do remind them that you're honestly spending more time capturing and sharing info than we may need to fix it, not to mention the time for us to see then reply, then rinse and repeat. Have them also consider about the "hourly" rate that if we're done in 15 mins, you'll pay only a quarter of that rate.
