Introduction
If you’re having trouble accessing Gamma, there may be several reasons behind the issue. This guide outlines the most common causes and how to resolve them to get back up and running quickly.
What is Connection Troubleshooting?
🌀 Insight: Connection troubleshooting involves identifying and resolving issues that prevent Gamma from loading or functioning properly.
This includes checking your network, antivirus software, firewall settings, and browser extensions.
How to Troubleshoot Connection Issues
Step 1: Check Antivirus Exceptions
Some antivirus software may mistakenly block Gamma.
Open your antivirus software settings.
Add an exception for Gamma.

Step 2: Test Your Firewall
Firewalls can sometimes block requests to Gamma.
Temporarily disable your firewall and reload Gamma.
Alternatively, try connecting to Gamma from a different network (e.g., using a mobile hotspot).
If the firewall is the issue, follow your firewall’s documentation to allow Gamma.
Step 3: Disable Browser Extensions
Extensions may cause compatibility issues.
Open an incognito window or use a different browser without extensions.
If Gamma works, disable extensions one by one to identify the culprit.
Step 4: Clear Cache & Cookies
Corrupted cache files can interfere with Gamma loading.
Go to your browser settings.
Clear your cache and cookies.
Refresh the page.
Step 5: Wait & Retry
If all else fails, wait a few minutes and try again. Temporary server issues or internet instability might resolve themselves.
Blocked by Cloudflare?
🔷 Note: Gamma uses Cloudflare for security. Cloudflare occasionally challenges or blocks access when a browser, network, or IP appears bot-like. There is no tool on Gamma's side to un-block a specific IP address — the fix is always on the user's end. The steps below resolve the vast majority of cases.
Check these special cases first
Your region: Gamma's Cloudflare intentionally challenges traffic from some regions (including Russia and Indonesia). If you're in a challenged region, connecting through a VPN that exits outside that region resolves it immediately.
AI browsers and the ChatGPT connector: If you're accessing Gamma through the ChatGPT connector or an AI-controlled cloud browser, Cloudflare challenge loops are expected bot-protection behavior, not a bug. Use a standard browser to access Gamma directly.
Step 1: Turn off any VPN or proxy
Turn off any VPN or proxy and retry. Or switch to a mobile hotspot — this is a good way to isolate whether the issue is with your network or IP.
Step 2: Try a regular browser window
Try a regular (non-incognito) browser window with extensions disabled, especially ad blockers and privacy tools. Or try a completely different browser.
Step 3: Allow third-party cookies and JavaScript
Allow third-party cookies and JavaScript for gamma.app and the Cloudflare challenge domains: challenges.cloudflare.com, google.com/recaptcha, and hcaptcha.com.
Step 4: Clear cookies and cache
Clear cookies and cache for gamma.app, then reload fresh.
Step 5: Check device date and time
Check that your device date and time are set to automatic. An incorrect system clock can trigger Cloudflare security challenges.
Step 6: Restart your router
This assigns a new IP address, which can resolve IP-reputation blocks on residential connections.
Step 7: Try a different device and network
Try a completely different device on a different network to isolate whether the issue is specific to your environment.
What should my network allowlist to access Gamma?
If you're on a corporate, school, or otherwise managed network, your IT team may need to allow Gamma through your firewall, proxy, or DNS filter.
🔷 Note: Gamma does not publish a list of static IP addresses. Our infrastructure uses cloud services and content delivery networks whose IP addresses change, so allowlisting by IP is not reliable. Please allowlist by domain instead.
Ask your IT team to allow the following:
Captcha services used at login: google.com/recaptcha, hcaptcha.com, and challenges.cloudflare.com
💎 Pro Tip: If Gamma loads on a personal hotspot but not on your work network, that confirms the issue is with your network's security settings rather than with Gamma or your device.
Which email addresses should I allowlist?
If you're not receiving emails from Gamma, such as workspace invitations, notifications, or replies from our Support team, your email provider may be filtering them. Add the following to your email allowlist (also called a safe senders list):
The gamma.app domain
If you use a corporate email system, your IT team may need to add these at the organization level.
FAQs & Common Issues
Why is my antivirus blocking Gamma?
Some antivirus programs may incorrectly flag Gamma as a threat. Adding Gamma to the safe list usually fixes the issue.
What if Gamma only works on a different network?
This suggests your firewall or network settings are blocking Gamma. Adjust those settings or consult your network admin.
Can browser extensions really block Gamma?
Yes, some ad blockers or script managers can interfere with Gamma’s loading. Try disabling them or using a different browser.
Can Gamma provide a list of IP addresses to whitelist?
No. Gamma's IP addresses are not static, so we recommend allowlisting *.gamma.app as a hostname instead. This is more reliable and covers the app, the API, and published content.
I'm not receiving emails from Gamma. What should I do?
Check your spam or junk folder first. If the emails aren't there, add the gamma.app domain, hello@gamma.app, and support@gamma.app to your safe senders list, or ask your IT team to allowlist them at the organization level.
