Tag mismatch error with ssl android studio - problem with wifi

Question

Packages to install:

• Android Emulator (emulator)

Preparing "Install Android Emulator (revision: 30.5.4)". Downloading https://dl.google.com/android/repository/emulator-windows_x64-7243153.zip An error occurred while preparing SDK package Android Emulator: Tag mismatch.: "Install Android Emulator (revision. 30.5.4)" failed: Failed packages:

I am getting such errors while downloading or updating anything in android studio.

but when I connect with my mobile data it works.

so maybe the problem is with my wifi.

also when I download anything in google chrome it says network failure again and again even if the internet speed is 30mbps.

My internet connection is very good but maybe it's a problem with the firewall or something.

Long time ago, I struggled with the same thing until I came up with a solution.

I assume your proxy performs SSL Inspection using custom root CA certificate and by doing so, Android Studio and/or JRE does troubles.

First, you need to export that custom certificate to a file: Simply browser to some site (let's say www.google.com ), then download the root certificate to a file. Found some instructions online: https://www.esri.com/arcgis-blog/products/bus-analyst/field-mobility/learn-how-to-download-a-ssl-certificate-for-a-secured-portal/

Second, get Android Studio to trust this certificate by adding it to accepted certificates list in Server Certificate preferences section.

Now configure your proxy in HTTP Proxy preferences section - I believe “Auto-detect proxy settings” is enough.

Finally, and that's the hard part, get your JRE to trust the certificate. Locate your JDK folder (File -> Project Structure), then install the certificate to the JRE's key store.

Windows CMD (password is changeit ): keytool.exe -importcert -alias MY_ALIAS -file PATH_TO_CERT_FILE -keystore PATH_TO_JDK_FOLDER\jre\lib\security\cacert

Mac terminal (password is also changeit ): sudo keytool -import -alias MY_ALIAS -file PATH_TO_CERT_FILE -keystore PATH_TO_JDK_FOLDER/Contents/Home/jre/lib/security/cacerts

Crossing my fingers that it'll work:) If not, I'll delete my answer so please keep me posted.

Whenever i used my wifi it showen me this error. Also my os use to show wifi connection is not secure. I've fixed this by using different wifi connection.
