iFix 8.0.0.0-MFPF-IF202010151343 introduces a breaking change with respect to compatibility with older versions of the Mobile Foundation server. If your app uses any of the following SDKs - Android, iOS or Cordova version 8.0.2020101412 or higher, it is necessary to upgrade your server version to 8.0.2020101311 or higher.
这是APAR PH30473 STRENGTHENING PRE-AUTH ENDPOINT所必需的，它更改了 Mobile Foundation SDK 和 Mobile Foundation 服务器之间的通信协议。
如果您无法升级您的服务器，作为兼容性措施，您可以通过添加以下配置：
Native Android apps
Add the following line to your mfpclient.properties file:
sdkProtocolVersion=1
Native iOS apps
Add the following entry to your mfpclient.plist
Name - sdkProtocolVersion
Type - Number
Value - 1
Cordova apps
Add the following line under the section of your project's config.xml.
mfp:SDKProtocolVersion1</mfp:SDKProtocolVersion>
The recommended approach is to upgrade the server and not use the compatibility configuration mentioned above.
Web Apps :
add sdkProtocolVersion : '1' in wlInitOptions
For more details see here https://mobilefirstplatform.ibmcloud.com/blog/2018/05/18/8-0-master-ifix-release/#changes-in-this-ifix-4
To resolve your issue :
Connect app with new version of app + set sdkProtocolVersion to 1
Or
Upgrade server to latest version.
