Elasticsearch sink does not recover from failure to create index template about serilog-sinks-elasticsearch

Today had to set AutoRegisterTemplate = false because elsewise it would cause a total crash. Even in try-catch block it couldn't recover from it. Version is 3.0.134.

And what did you experience? What kind of crash?

Here is some context:

• implemented a wndows service with topshelf
• registered serilog with AutoRegisterTemplate = true
• the elastic search server is from elastic cloud (SaaS)

When I started the service (deployment with Octopus deploy) the service logged a log message before the logger creation but nothing after that. The process died without any successive log messages and Octoups reported simply: cannot start service.
I also checked eventlogs without luck. The only thing that worked is to remove AutoRegisterTemplate. No problems since then.

Did you try to enable the selflog (https://github.com/serilog/serilog/wiki/Debugging-and-Diagnostics) of Serilog? The sink will log errors to this selflog and it might contain details.
