I'm using the AWS_S3 signature calculator by JackKirk: https://www.b4x.com/android/forum/t...re-calculator-b4x-works-on-b4a-b4i-b4j.81272/ and OkHttpUtils2 (2.92) to download files from an AWS S3 bucket in my published app (https://play.google.com/store/apps/details?id=com.planlauf.derlousberg). Everything is working without a problem for weeks now but a couple of days ago I had more than 20 crashes on two devices running Android 8 and 10 on a single day (but none since). Google Play Console reports an IllegalArgumentException at okhttp3.Headers$Builder.checkNameAndValue.
Has anyone experienced something like this? Could it be a AWS S3 problem instead of a bug?
Thank you!
