These days, Back 4 Blood players cannot even access the game as the SIGN IN error “The connection to the Profile Service cannot be established. Try again later.” kicks them out. PC gamers seem to be more likely to be affected. But some Xbox players are also suffering from this issue. To help you out, we’ve put together some fixes.
Before getting started, don’t forget to restart your PC and game. If a simple restart doesn’t give you any luck, try the fixes below.
- Check the server status
- Clear Steam download cache
- Verify integrity of game files
- Restart your router/ modem
- Update your network adapter driver
- Change your DNS server
1. Check the server status
Reports claim that the problem might be at the server end that it is down for maintenance. If that’s the case, there’s nothing you can do but patiently wait for the updates. You can check Steam and Back 4 Blood‘s Twitter posts for the updates.
If everything is running smoothly, move to the next fix for further troubleshooting.
2. Clear Steam download cache
Steam keeps temporary downloads and other files. These can be oversized if you usually use Steam and would cause some issues. To fix it, you can clear the cache.
- From your Steam client, click Steam > Settings from the top left client menu to open the Settings panel.
- Select the Downloads tab. Find the CLEAR DOWNLOAD CACHE button at the bottom and click on it.
- Click OK.
After clearing the download cache, restart your Steam client and check if you can access your game without receiving this SIGN IN error. If that error still pops up, try the next fix below.
3. Verify integrity of game files
When you’re having issues with launching your Steam games properly, you should try to verify your game files integrity. This process can make sure that the integrity of your game files is intact.
- Open your Steam client. Under LIBRARY, right-click your game title and select Properties.
- Select the LOCAL FILES tab. Then click on the button Verify integrity of game files….
Steam will now verify all of your game files, and compare them with files hosted on the game servers. If there are any discrepancies Steam will redownload, and repair corrupted files.
When the process is complete, launch your game. If your problem persists, try the next fix below.
4. Restart your router/ modem
If the fixes above don’t work for you, it’s time to check your network connection. First, try to restart your modem and router. What you need to do is unplug your router and modem, then wait at least 10 seconds and then plug your router and modem back in.
If your problem persists, proceed to the next fix.
5. Update your network adapter driver
When troubleshooting network connection issues, one of the basic steps you should take is to check if your network driver is outdated. Using outdated drivers will affect performance. If you can’t remember when was the last time you updated your network driver, definitely do it right now.
There are mainly two ways to update your network driver: manually and automatically.
To update your network adapter driver, you can either do it manually via the Device Manager or head to the manufacturer’s driver download page to download and install the exact driver for your system. This requires a certain level of computer knowledge and can be a headache if you aren’t tech-savvy.
You can do it with Driver Easy, an automatic driver updater tool. With Driver Easy, you don’t need to waste your time hunting for driver updates as it will take care of the busy work for you.
- Download and install Driver Easy.
- Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any devices with missing or outdated drivers.
- Click Update All. Driver Easy will then download and update all your outdated and missing device drivers, giving you the latest version of each, direct from the device manufacturer.
This requires the Pro version which comes with full support and a 30-day money-back guarantee. You’ll be prompted to upgrade when you click Update All. If you don’t want to upgrade to the Pro version, you can also update your drivers with the FREE version. All you need to do is to download them one at a time and manually install them.
After updating drivers, restart your PC and launch Back 4 Blood. If you’re still getting the error, try the next fix below.
6. Change your DNS server
If your ISP-supplied DNS servers are slow, or not properly configured for caching, they can effectively slow your connection. To avoid this, try to switch to a different server.
- On your keyboard, press the Windows logo + R keys simultaneously to open the Run box.
- Type control and press Enter to open the Control Panel.
- Click Network and Internet. (Make sure you set Category as your View by. )
- Find Network and Sharing Center and click it.
- Click on your Connections, whether it’s Ethernet, Wi-Fi, or others.
- Click Properties.
- In the Properties window, click Internet Protocol Version 4 (TCP /IPv4) and then click Properties.
- Click Use the following DNS server addresses:. Then type the following number.
Preferred DNS server: 188.8.131.52
Alternate DNS server: 184.108.40.206
Then check the box Validate settings upon exit and click OK.
After applying the changes, try to launch Back 4 Blood and you should be able to enjoy your gameplay without receiving any error messages.
