General Connectivity Troubleshooting

If you are running into problems starting a sim or more general website problems (network connectivity error, "an error occurred", "Seri didn't handle this error"), there are a variety of troubleshooting steps to take before contacting support.

Some specific known conflicts:

Check to see if any of these are in your taskbar applications or in your Start menu. If they are installed, run them and check their settings.

Intel Killer Intelligence Center - disable the "Prioritization Engine" and/or uninstall the program entirely. This is known to break sims on Raidbots.
NordVPN Threat Protection - this is known to cause some issues with various WoW-related websites. Disable it and try again.
Lenovo computers - Lenovo Vantage can interfere with Raidbots and cause the connectivity error. Run Lenovo Vantage and disable Network Boost.

General steps to determine what might be causing the issue:

Try force reloading the website. In most cases, Ctrl-Shift-R will perform a full reload.
Try doing a a full site reset using the Raidbots Reset tool.
Try using an incognito/private window. If this fixes the problem, the issue is probably a browser extension/plugin.
Try using a different web browser. If this fixes the problem, the issue is probably a browser extension/plugin.
Try using another computer or phone that you have available on the same network. If this works, there's probably some other 3rd party software on your computer causing the issue.
Try using another internet connection (cellular if you have a phone, neighbor's wifi if available, etc). If this solves the problem, there may be an issue with your network provider or a connectivity issue between you and the Raidbots servers
Pause/disable any 3rd party anti-virus/anti-malware software running. These can sometimes incorrectly categorize Raidbots traffic as a problem.
Pause/disable any VPN software you are using. These can sometimes cause network issues with Raidbots.
Alternatively, try using a VPN to a different country/location. If this works, there's probably some issue with your ISP.
Pause/disable any 3rd party Crypto software. These can do all kinds of weird/bad things.
Run anti-malware (like Malwarebytes) on your computer to clean up any possible malware.

If you are still having problems, please contact Raidbots Support and include the following information:

List of the services running on your computer (instructions below).

Manufacturer of your gaming computer (e.g. Lenovo, Alienware, self built)
The country you are in
Your residential and/or cellular network providers that were tested
Any additional info you can come up with.

These types of problems are extremely difficult for Raidbots to diagnose so please provide as many details as possible.
