After Seq Update - Service won't start

[koni668]

Hello there,

I'm running Seq version 4.1..17.0 on my Windows Server 2019 and decided to upgrade it.
I went on the website, downloaded the latest .msi for windows. Before I started the installation I created a snapshot and hit install.
Everything seemed fine, same directory, folder, standard settings, but when I opened the browser "internet explorer" it now doesn't let me reach the "https//localhost:5341" page.
I also noticed that the service changed from "Seq log Server" to "Seq". This service doesn't start.
Tried to start it manually, it shows "running" for a second and instantly stops.

Browser showing a DNS error with:
INET_E_RESOURCE_NOT_FOUND

that's probably because of the service I assume?
There doesn't seem to be an issue with the service account, since I read many "logon failure" threads, but I didn't get any errors here.
Any similar issues known or a way how to fix it?

Hi @koni668

There are a few steps involved in upgrading from Seq 4 to the latest version. See https://docs.datalust.co/docs/upgrading

You will need to upgrade to Seq 5.1, run the server for 24 hours, then upgrade to Seq 2022.1 and then upgrade to the latest version.
