Error 500.19 in server with IIS 10

se flag

I had a Web Service running in net 3.5 (I know, so old) and I migrate it to Net 4.6. I completed the migration in local, but when I deploy the web services in the server I get an 500.19 error. I review the log event, the traces, web.config... but I can´t figure out. Please, could you help me? Please, ask me for any extra information that you need as logs, traces, specifications, web.config,.... Many Thanks

There should be an HRESULT code. https://learn.microsoft.com/en-us/troubleshoot/developer/webapps /iis/health-diagnostic-performance/http-error-500-19-webpage

@GregAskew Thanks for your help. In the event viewer don´t exist anything relevant. Just something about Perf Net. In the request trace of the server there are plenty of information. I posted something that I think could be interesting, but if you want to help me I can post more. But I can´t find anything related with HRESULT. Thanks again
I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
