The windows builds that previously used to run now crash around 30-40s after bootup, for no apparent reason. Produces no errors too. Any thoughts on what might have changed between yesterday and today to cause this?
Though I expected this to be some issue with TravisCI, it seems that it is because I have added a secure environment variable as explained in Docker Windows containers on Windows. Looking forward to this fix.
As there was no reply for over 2.5 months, we moved the failing builds to Azure Pipelines. The migration path is straightforward for anyone who may be interested.
