Troubleshooting Common GEDmatch Errors

Troubleshooting Common GEDmatch Errors

Site Access Errors
403 Error / "Bot Detection" Block

      Symptom: You receive a 403 error or a message indicating you have been identified as a bot and cannot access the site.
      Cause: GEDmatch has security measures in place to prevent automated access. These can sometimes be triggered by normal browsing activity, such as rapidly navigating between pages or running multiple searches in quick succession.
      Solution:
      •      Wait 24 hours and try again. The block typically resets automatically.
      •      Clear your browser cache and cookies before attempting to access the site again.
      •      If the issue persists after 24 hours, contact GEDmatch Support (support@gedmatch.com) with the email address on your account.
 

Upload Errors

"Upload disabled until chosen DNA-file has been processed"

      Cause: You have a DNA file currently being processed. GEDmatch does not allow uploading a new file while a previous upload is still processing.      
      Solution: Wait for the current upload to finish processing (typically 24–48 hours). Once it is complete, you will be able to upload additional files. If this message persists for more than 48 hours, it may indicate a processing error. Clear your browser cache and cookies and check again. If it still shows after 2+ days, contact GEDmatch Support with your kit number for investigation.


Upload page not responding or times out

      Solution:
  1. Clear your browser cache and cookies. This resolves most upload issues.
  2. Try using a different web browser (Chrome, Firefox, or Edge).
  3. Use a laptop or desktop computer rather than a mobile device — the upload function works best on desktop browsers.
  4. If the issue persists, try again later. Occasionally the system may be under heavy load.


"Please select a Source from the list"

      Cause: The DNA source drop-down menu on the upload page was not selected.
      Solution: Select your DNA testing company from the drop-down menu (e.g., AncestryDNA, 23andMe, FTDNA). If your company is not listed, select "Other" and type the name manually.


"Failed HTZ ratio test" / Kit rejected after upload

      Cause: The uploaded DNA data file did not pass GEDmatch's quality checks. This can happen if the file is corrupted, incomplete, or not in the expected format.      
      Solution:
  1. Re-download the raw data file from your DNA testing company.
  2. Make sure you are downloading the Autosomal DNA raw data (not Y-DNA or mtDNA).
  3. Upload the freshly downloaded file to GEDmatch.
  4. If the issue persists, the file from your testing company may have a quality issue. Contact your testing company for a new copy of your raw data.

      Cause: You are attempting to upload a family tree (GEDCOM) file through the DNA data upload page, or vice versa.      
      Solution: GEDmatch has separate upload pages for DNA data and GEDCOM files. Make sure you are using the correct upload page for the type of file you are uploading. The DNA upload page expects raw DNA data files (.txt, .csv, .zip). The GEDCOM upload page expects .ged files.

 

Kit and Account Issues

"Invalid kit number" when using tools

      Cause: The kit number may be entered incorrectly, the kit may have been deleted, or the kit's access status may not permit the action you are trying to perform.
      Solution:
      •      Double-check the kit number for typos.
      •      If you are trying to compare with someone else's kit, their kit may be set to Private status, which prevents other users from accessing it.
      •      Ask the kit owner to change their kit's access status to Public or Research if they want to be compared.


Kit shows "Research" status — some tools not working

      Cause: Kits set to "Research" have limited visibility. They can be used in One-to-One comparisons by other members, but they do not appear in One-to-Many match lists and cannot be used with some tools.
      Solution: To change your kit status:

  1. Log in to GEDmatch.
  2. Click the pencil icon next to your kit number.
  3. Select your preferred access status (Public options allow the most functionality).
  4. Save the changes.


Kits disappeared / "No kits found"

      Cause: This can happen if you logged in with a different email address than the one your kits are registered to, or if you created a new account instead of logging in to your existing one.
      Solution:
      •      Make sure you are logging in with the same email address you originally used to create your GEDmatch account and upload your kits.
      •      If you use a social login (Google or Yahoo), make sure you are clicking the correct social login button — logging in with a different method can create a separate, empty account.
      •      Contact GEDmatch Support if you cannot locate your kits. Provide your kit number (if you have it) and both your old and new email addresses.


Admixture / Heritage calculator not working for a kit

      Cause: The kit may be flagged as a duplicate, or there may be a data issue with the kit.
      Solution:
      •      Check if the kit is a duplicate of another kit in your profile. Duplicate kits have reduced functionality.
      •      Try using a different kit if you have multiple kits uploaded.
      •      Contact support with your kit number for investigation.

 

Website and Browser Issues

"Manage Membership" page shows blank

    Cause: This is a known issue that occurs primarily on mobile devices and some browsers.
    Solution:
      •      Access the page from a laptop or desktop computer.
      •      Try a different browser (Chrome, Firefox, Edge).
      •      Clear your cache and cookies, then try again.
      •      If the page still won't load, contact GEDmatch Support to manage your membership.


Website is slow or not loading

      Solution:      
      •      Check if GEDmatch is experiencing downtime by waiting a few minutes and trying again.
      •      Clear your browser cache and cookies.
      •      Try a different browser or disable browser extensions that might interfere.
      •      The website works best on desktop browsers. Mobile browsers may not support all features.


Cannot type in the email field on the login page

      Cause: A browser extension or auto-fill feature may be interfering with the email input field.
      Solution:
      •      Try a different browser or use an incognito/private browsing window.
      •      Disable browser extensions temporarily, especially password managers or form auto-fill tools.
      •      For more details, see our article: "Why am I not able to type in my email on login."

 

Not receiving password reset emails

      Solution:
      1.   Check your spam/junk folder — password reset emails sometimes get caught by spam filters.
      2.   Add support@gedmatch.com and noreply@gedmatch.com to your email contacts or whitelist.      
      3.   If you use Gmail, check the Promotions and Updates tabs.
      4.   Try requesting the reset again after a few minutes.
      5.   For more details, see our article: "What to do if your password reset email is not received."


Not receiving verification emails

      Solution: Same steps as above. Verification emails may take a few minutes to arrive. Check spam/junk folders and email tabs.
