Deployment with truffle to rinkeby not working

Currently I have a lot of problems with deployment over truffle to rinkeby.
Last week it worked fine but now my deployment is running forever.
Here are my settings:

    networks: {
    rinkeby: {
      // provider: () => new HDWalletProvider( mnemonic, `wss://${infuraKey}`),
      provider: () => new HDWalletProvider(mnemonic, `${infuraKey}`),
      gas: 5000000,
      gasPrice: 25000000000,
      network_id: 4,
      skipDryRun: true, // Skip dry run before migrations? (default: false for public nets )

And the current console output:

Thanks a lot!
