Can't find the distribution certificate used in the backend **The iOS Distribution Certificate used in the backend should ALWAYS be visible in [http://developer.apple.com](http://developer.apple.com) > Certificates, Identifiers & Profiles > Certificates** This is true both in Apple Developer accounts ($99/year) and Apple Enterprise Developer accounts ($299/year). ​**When an iOS Distribution Certificate is revoked in the Apple Developer account, it may still appear as valid in the backend.** The backend only registers the creation and expiration date of a certificate to be able to tell you when it's expired. The backend is not connected with your Apple Developer account. **If you can't find the iOS Distribution Certificate used in the backend:** 1 - Verify that you are logged into the right Apple Developer account/in the right Team. (If you were in the wrong account or team, log into the right one and check again!) 2 - [Renew the iOS certificates](https://www.goodbarber.com/help/publish-your-ios-app-yourself-solo-r75/renew-your-ios-certificates-a101/) (or [ask GoodBarber to do it for you](https://www.goodbarber.com/help/goodbarber-takes-care-gbtc-publication-service-r80/request-ios-certificate-renewal-gbtc-service-a298/) ) ![](https://cmsphoto.ww-cdn.com/superstatic/1663330/art/default/27992401-27876609.jpg?v=1654682670.3945034) ## 2. The date of the mobile provision doesn't match with the distribution certificate In a regular Apple Developer account ($99/year), the iOS Distribution Certificate and Mobile Provision files are valid for 1 year. Therefore, they should have the same expiration date (+ or - 1 day). In an Apple Enterprise account ($299/year), the distribution certificate is valid for 3 years and the Mobile Provision file is valid for 1 year. Therefore, the dates don't necessarily match. ![](https://cmsphoto.ww-cdn.com/superstatic/1663330/art/default/27992401-27876607.jpg?v=1654682670.6282916) **If the expiration dates don't match:** 1. Go to [http://developer.apple.com](http://developer.apple.com) **> Certificates, Identifiers & Profiles >** **Profiles** 2. Select the **App Store Mobile Provision file** of your app 3. Choose the**Distribution Certificate used in the backend (with the same expiration date)** 4. Generate the**new App Store Mobile Provision file** and download it. 5. Delete the old **Mobile Provision file**from the backend and **upload the new one.** **Warning:** If the app is being distributed internally (using an Apple Enterprise account - $299/year), continue the iOS submission process until the end and send the new version of the app to your users. ![](https://cmsphoto.ww-cdn.com/superstatic/1663330/art/default/27992401-27876608.jpg?v=1654682670.8882093) ## 3. Two distribution certificates have the same date in the developer account **You should NEVER create 2 iOS Distribution Certificates on the same day!** In this case, even if the date of the Distribution Certificate and the Mobile Provision files match, the build may still fail. When 2 iOS Distribution Certificates are created on the same day: => they have the same date. => it is impossible to know which one you uploaded in the backend. => it is impossible to know which one to choose when creating the Mobile Provision files If 2 iOS Distribution Certificates have the same date: 1 - Revoke both of the Distribution Certificates with the same date 2 - [Renew the iOS certificates](https://www.goodbarber.com/help/publish-your-ios-app-yourself-solo-r75/renew-your-ios-certificates-a101/) (or [ask GoodBarber to do it for you](https://www.goodbarber.com/help/goodbarber-takes-care-gbtc-publication-service-r80/request-ios-certificate-renewal-gbtc-service-a298/) ) **Warning: If your app is for Internal Distribution (using an Apple Enterprise account - $299/year), the current version of the app will stop working from the moment you revoke the certificate in use.** Continue the iOS submission process until the end and send the new version of the app to your users. ![](https://cmsphoto.ww-cdn.com/superstatic/1663330/art/default/27992401-27876610.jpg?v=1654682670.991668) ## 4. Too many boxes checked in the App ID If all the above is correct, maybe the problem is the App ID. 1- Go to **[http://developer.apple.com](http://developer.apple.com) > Certificates, Identifiers & Profiles >Identifiers** 2 - If there are other boxes checked except the**2 default ones** and **Push Notifications**, uncheck them (You will need to scroll down to see the entire list) 3 - Go to the menu**Profiles** 4 - Select the **App Store Mobile Provision file** of your app 5 - Make sure you have the right **iOS Distribution Certificate** and **App ID** 6 - **Save** and **download** the**new App Store Mobile Provision file**. 7 - In the backend, **delete** the**old App Store Mobile Provision file**and**upload the new one.** **Warning:** If the app is being distributed internally (using an Apple Enterprise account - $299/year), continue the iOS submission process until the end and send the new version of the app to your users. ![](https://cmsphoto.ww-cdn.com/superstatic/1663330/art/default/27992401-28091173.jpg?v=1654682671.1233652) ## 5. Everything looks Okay, but the build fails If you carefully verified all the points mentioned above, and the build keeps failing: 1. Go to **[http://developer.apple.com](http://developer.apple.com) > Certificates, Identifiers & Profiles** 2. Go to the menu **Certificates** > take a **screenshot showing ALL the iOS Distribution certificates** 3. Go to the menu **Identifiers** **> select your App ID >**take screenshots**of ALL the capabilities** 4. Go to the menu**Profiles** **> select your App Store Mobile Provision file > take a** **full page screenshot** Contact the Support , explain your problem and provide all the screenshots listed above (you can send them all at once in a .zip file).
