Akamai restricting my access to steam

wait?
move?
change isp?
get new ip from current isp?
use vpn/proxy? (preferably one in your country for safety)

Only thing I can think of is getting a new IP. So maybe charging ISP? Alternatively you can try calling them and starting the conversation saying that you want to cancel the service, from there you might be able to negotiate a new IP, they're usually a lot more willing to help you if they feel like it's either that or losing a client.

The reputation score at Akamai should gradually return to normal if you do not perform any other suspicious "attacks" on their network. How long that takes is a mystery and may depend on the IP reputation of your neighbors on your network/ISP/country. Could be days or weeks.

If you post at https://community.akamai.com/ perhaps an Akamai employee can help look up more details. I have seen them help people there in the past.

Have you tried to force an IP change? Some people recommend unplugging your modem for minutes/hours but I found that changing the router's MAC address usually works immediately.

So good news, you aren't "blocked", you've probably been detected as a bot network, and "i´m pretty sure it´s releated to the use i made with Steam API" makes it sound like you know exactly why. Obviously, don't do this in the future. Now this should clear up on its own, but it could take weeks to months if you tripped a really high threat rating (and this will reset every time you trip a threat rating again, for example by continuously trying to connect). That's what Akamai does, it isn't just a CDN, but also the first few layers of security for a lot of big companies.

Your best option is to change your IP address, period. The only person who could fix this from Steam or Akamai is going to be a relatively high level engineer in the security ops center at Valve Inc, and you will never get on the phone with them unless you know them personally. It wouldn't make sense to fix this for you, you're a bot network, why would anyone help you? This is literally their job to block you.

Luckily, unless your ISP is secure as hell (extremely unlikely) and refuses to use DHCP, you should be able to change your IP trivially on your end using ipconfig on windows, ifconfig on linux, or just unplugging your router for 5-15 minutes depending on their lease renewal time. There are tons of tutorials for this online. If that doesn't work then your IP can still be changed by your ISP directly, or you could always cancel and reopen your account.

What others have said… you’ve probably been getting info from steam in such a way that the server thinks you’re a bot or hacker.
It’s restricted access- in this case completely, and if you’re lucky, access will be restored as long as you give it a cool-down period.
If it’s been from the particular app you’ve been using and you still want to use this app, then chances are the same block will happen again. Continued use could cause more severe blacks/bans.

At this stage all you can do is wait.

I guess this is something the game launcher (or whatever is used to import the data) should fix to prevent this from happening again.

May I ask which game launcher it is? I know Playnite and GOG Galaxy can handle multiple libraries.

This is a bit off topic, but during the Christmas and New Year holidays, the number of people complaining of such line problems increases rapidly.

It is possible that there is a zero-day glitch in your router or modem that is being exploited.

In any case, it is better to reset the router or modem in your spare time before using it.
(They are often exploited when the system is overloaded).⚡💻⚡☎

Of course, don't forget to reboot all your computers, smartphones and IT appliances to see if anything strange is going on, and do a security scan if possible.

P.S. There is another problem if the connection is from China.📝

The sad reality is that a handful of CDNs/cloud-providers nowadays have almost complete control over the internet (Akamai, CloudFlare, AWS, ..); it's basically a centralized point of failure that goes against the idea of a resilient internet...

Have you noticed lately that whenever a popular CDN service has an outage, half of the internet goes down with it?

Have you noticed how whenever you browse the web using Tor/VPN or just choose to block Javascript you will get an unusual amount of captchas and wait-while-we-verify-you-are-not-abuser blockpages!

CF is a particular offender here, they have grown massively obliterating all competition by offer many bundled services for free (CDN, caching, reverse proxy, DDOS protection, domain registrar, DNS resolver, SSL certificates, etc.).

If for whatever reason you find yourself "blacklisted" by one of these CNDs you will have a very hard time accessing large parts of the web.

No one entity should have that much control over the whole infrastructure! It's a global threat to privacy and freedom of information.
