Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

cdn.unrealengine.com blocked in Russia (by IP)

It's not a bug, but I think it's a good thing to inform Epic about this issue. In Russia providers are forced to block some websites (Russian Internet Restriction Bill). And due to nature of DPI they're using, it's a common thing to block by IP.

Unfortunately for me (and possibly Epic), cdn.unrealengine.com shares same IP (52.85.239.118) with other website that was blocked by the provider (thank you cloudfront!). This causes setup.bat to fail to download the binaries from Epic's servers.

This probably will affect a miniscule amount of users. Since this domain used only for GitHub binaries distribution, and not every provider using blocking by IP.

To solve the issue, users could override the IP by one of the mirrors by adding a new record in HOSTS file (thank you cloudfront!):

54.192.130.105 cdn.unrealengine.com

^ this one worked for me, I've used ping for each of the IP addresses to find closest one (with lowest time delay)

Cloudfront uses several different servers and DNS server provides You the matching IP of the most closest one.

Have fun! (ironically)

Also, addition, if someone using a dd-wrt based router, he could enable DNSMasq add a records:

address=/cdn.unrealengine.com/54.192.130.105

address=/cdn1.unrealengine.com/54.192.130.105

Then it will be available on any device connected through it.
