My Screenly display is running a basic html page, which is set to refresh every 60 seconds (with a meta tag in the header). Generally this works fine, but occasionally I come back to it and it has an error, “Error resolving ^amywebsite.domain.com^a: Temporary failure in name resolution.” The “^a” is a single character, as described here: string - What is this character ( Â ) and how do I remove it with PHP? - Stack Overflow
Not sure if those weird characters are indicative of the problem, or just a result of the error displaying weirdly. I have added the site URL in the hosts file, so there should not be a DNS issue.
