在unity里调试一切正常 生成的exe也一切正常 但生成web版本 就连接不了 查看log看到的是

MethodAccessException: Attempt to access a private/protected method failed.
   at System.Security.SecurityManager.ThrowException (System.Exception ex) [0x00000] in <filename unknown>:0  
   at RACTCPPacketData..cctor () [0x00000] in <filename unknown>:0
Rethrow as TypeInitializationException: An exception was thrown by the type initializer for RACTCPPacketData
   at RACTCPPeerMgr..cctor () [0x00000] in <filename unknown>:0
Rethrow as TypeInitializationException: An exception was thrown by the type initializer for RACTCPPeerMgr
   at NetMsgProcMgr.Update () [0x00000] in <filename unknown>:0
