Nop 4.0 - HTTP Error 502.5 - Process Failure

Hi,

I can not start version 4.0 (3.9 - works fine)
What ideas?

HTTP Error 502.5 - Process Failure


Common causes of this issue:

The application process failed to start
The application process started but then stopped
The application process started but failed to listen on the configured port

Troubleshooting steps:

Check the system event log for error messages
Enable logging the application process' stdout messages
Attach a debugger to the application process and inspect

Thanks :)

I had this same error come up when trying to run nopCommerce 4.0 through IIS.

After reading an article on https://stackify.com/how-to-deploy-asp-net-core-to-iis/, I reviewed my file layout versus a working nopCommerce 4.0 site, and realized I still needed to publish Nop.Web. Based on how I used to setup sites in 3.9, I published the site directly into the Nob.Web folder, and I was able to load up the site.

Hope this helps.

To run nop v4.0 with IIS there are two ways to do it:

1-Publish Nop.Web into the folder pointed by your IIS website (mentioned in prior post).

2-Point your website to your development Nop.Web folder and install "Enable development-time IIS support". More info here:
https://docs.microsoft.com/en-us/aspnet/core/publishing/development-time-iis-support

I came across the exact same error trying to compile and run the 4.0 source code version for the first time.

For me this error was caused because I had changed the "Platform target" of the nop.web build from the 4.0 default setting of "x86" to what I was used to using which was "Any Cpu". Changing this dropdown back to either x86 or x64 stopped this error from occurring for me and allowed me to run 4.0 without issue.

While the original post is about running 4.0 in iis, I thought I'd add this to the discussion for anyone searching for the error code as in both cases they are the same.

Hello guyes,

I faced same error that you guyes faced.

I solved with download .Net core windows server hosting bundle from this link https://docs.microsoft.com/en-us/aspnet/core/publishing/iis?tabs=aspnetcore2x#common-errors


Thank you,

Also check and compare this line in the web.config file

    <aspNetCore requestTimeout="00:07:00" processPath=".\Nop.Web.exe" arguments="" forwardWindowsAuthToken="false" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" />

If you copy web.config from the source version it will read like this

<aspNetCore requestTimeout="00:07:00" processPath="%LAUNCHER_PATH%" arguments="%LAUNCHER_ARGS%" forwardWindowsAuthToken="false"
                stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" />

i have publish my app ... it was working fine .... Same problem came across to me even my local system as well published site facing the same problem ...

i am working on my development environment but still not find solution...

did you check log under Log folder of your root directory?

if not than,

set stdoutLogEnabled="true" under web config and see the error.

hope, it would be helpful.

yes i have change it to true...
