Experiencing the same issue here. Archiving and uploading to itunnesConntect take from 3 to 4 hours !!! while it use to take less than half hour. The size upload which is .api + dSYM = less than 200 Mb. Im uploading via fastlane and using the "--verbose" and I see that the upload goes to 15% then it shows an error [Transporter Error Output]: An un-handled exception occurred: java.net.SocketTimeoutException: Read timed out for (id: ... And it keeps retrying for a long while, until it finally succeeds from 0% to 100% with no errors and it takes more than 1 hour . I was not like this before at least before xcode 10, and my internet connection is not bad. Thank you.

As you can see here, a recent upload took 12068.786113 seconds means more than 3 hours <testcase classname="fastlane.lanes" name="0: defaultplatform" time="0.000359"> </testcase> <testcase classname="fastlane.lanes" name="1: incrementbuildnumber" time="1.35417"> </testcase> <testcase classname="fastlane.lanes" name="2: buildapp" time="864.403763"> </testcase> <testcase classname="fastlane.lanes" name="3: uploadtotestflight" time="12068.786113"> </testcase> macOS: 10.15.6 (19G2021) XCode: Version 12.0 (12A7209)

Thanks, but after I added the Privacy - Local Network Usage Description I was expecting to see a popup, but I've got nothing. Is that ok ?
