I currently have error code 5c and i cant play any games on league. I cant sign on to even message anyone for a ticket or to get support. So i'm hoping someone see this. I have reset my network. Reinstalled my game. the error is still there everytime i try to play.
Disabling windows firewall worked for me
I am in the same boat I tried doing what other pages said like a month ago but no fix
Same problem here, this seemed to be a problem in EU for a while and reading the old forum post didn't help at all.
so just an update to you all I found a way around it and its not the greatest fix but it seemed to work. A. Disable all security feature your router and computer offer (i don't recommend this) or B. try hard lining in and completely skipping your router just going directly from your modem
currently having the same issue...not sure I was playing a game like an hour ago and took a break came back and now I cannot play
Having the same issue. Also I noticed captchas are popping up from Cloudflare based CDNs, including Riot's own site.
My guess is that the League client uses a Cloudflare based CDN to handle user data, and Cloudflare at some point overnight fucked up and blacklisted a ton of IP addresses on accident. Noticed I'm getting 403s returned from the majority of CDN based GET requests which supports my theory since 403s signify unauthorized requests usually from blocked/forbidden IPs.
This doesn't seem to be an issue Riot can fix, but rather it is an issue on the end of whichever CDN they use (probably Cloudflare/AWS).
edit: Generally Cloudflare blocks IPs if they were associated with DDoSing. I have a feeling that overnight a massive DDoS attack occurred where thousands of IP addresses were spoofed during the attack, resulting in them being blacklisted this morning.
Having the same issue with error code 5c as well as cloudfare captcha on multiple websites.
Have the same issue here and i just played a game but then i got back to the lobby it said error 5C...
