I experienced this error when trying to execute Material from Chemical Name or SMILES protocol inside Materials studio (from a Linux cloud server)

Class SciTegic.MolNameParser not registered. Creation of component SciTegic.MolNameParser failed -> 'Molecule from Chemical Name' ('Molecule from Chemical Name'); Location: 32:0 - error during Initialization phase CProtocolBaseImpl::PassDataDownstream: Pipeline Pilot exception rethrown CProtocolStd::onProcess: Pipeline Pilot exception rethrown CProtocol::onProcess: Pipeline Pilot exception rethrown -> 'Subprotocol' ('Create Material'); Location: 32 - error during Data Record Processing phase CProtocolStd::onProcess: Pipeline Pilot exception rethrown CProtocol::onProcess: Pipeline Pilot exception rethrown CComponentRunner::CallProtocolOnProcess: exception caught, calling onFinalize before rethrow Protocol Material from Chemical Name or SMILES

There's also another issue when executing the default Calculate Glass Transition Temperature protocol:

All remote servers have failed.
CRemoteProtocol::onProcess: Pipeline Pilot exception rethrown
CProtocol::onProcess: Pipeline Pilot exception rethrown
-> 'Subprotocol' ('Equilibration'); Location: 120:0 - error during Data Record Processing phase
CProtocolStd::onProcess: Pipeline Pilot exception rethrown
CProtocol::onProcess: Pipeline Pilot exception rethrown
-> 'Subprotocol' ('Equilibration'); Location: 120 - error during Data Record Processing phase
CProtocolStd::onProcess: Pipeline Pilot exception rethrown
CProtocol::onProcess: Pipeline Pilot exception rethrown
CComponentRunner::CallProtocolOnProcess: exception caught, calling onFinalize before rethrow

Anyone know what is the reason causing these issues?
