Hi,
Overnight one of our websites started to crash permanently, it is running on version 7.5.11 and we are hosting it on Azure Web Apps.
The error message says:
Exception type: IOException Exception message: An unexpected network error occurred. at Umbraco.Core.Cache.HttpRuntimeCacheProvider.GetCacheItem(String cacheKey, Func1 getCacheItem, Nullable1 timeout, Boolean isSliding, CacheItemPriority priority, CacheItemRemovedCallback removedCallback, CacheDependency dependency) at Umbraco.Core.Cache.HttpRuntimeCacheProvider.GetCacheItem(String cacheKey, Func1 getCacheItem, Nullable1 timeout, Boolean isSliding, CacheItemPriority priority, CacheItemRemovedCallback removedCallback, String[] dependentFiles) at Umbraco.Core.Cache.DeepCloneRuntimeCacheProvider.GetCacheItem(String cacheKey, Func1 getCacheItem, Nullable1 timeout, Boolean isSliding, CacheItemPriority priority, CacheItemRemovedCallback removedCallback, String[] dependentFiles) at Umbraco.Web.PublishedCache.XmlPublishedCache.PublishedMediaCache.GetCacheValues(Int32 id, Func2 func) at Umbraco.Web.PublishedCache.XmlPublishedCache.PublishedMediaCache.GetUmbracoMedia(Int32 id) at Umbraco.Web.PublishedCache.XmlPublishedCache.PublishedMediaCache.GetById(UmbracoContext umbracoContext, Boolean preview, Int32 nodeId) at Umbraco.Web.PublishedCache.ContextualPublishedCache1.GetById(Boolean preview, Int32 contentId) at Umbraco.Web.PublishedContentQuery.DocumentById(Int32 id, ContextualPublishedCache cache, Object ifNotFound) at Umbraco.Web.PublishedContentQuery.Media(Int32 id) at Umbraco.Web.UmbracoHelper.Media(String id)

The media file exists, and republishing the home node brought the site back online.
Has anyone experienced something similar, or any ideas what the root cause is?
Thanks, Rachel
Same thing happened to us today we are on 7.5.10. Not sure why but found your post when I was researching.
We have now experienced this error 3 times within a 3 week period.
Azure Support are saying this is an Umbraco issue / bug as they are not able to find any platform issues.
We really want to know why this error is occurring and what is the root cause.
Hello,
We also had this problem ( version 7.5.3 ). Any one have anymore information about it?
After an app-pool recycle the message was gone. Would like to know how we can avoid this in the future.

We implemented the configuration changes detailed here: https://stackoverflow.com/questions/43629446/umbraco-an-unexpected-network-error-on-azure-web-apps
Since making the configuration changes we've not encountered the "unexpected error" which used to occur every couple of weeks.
