Node 1 is not in your graph. I suspect that Node '1' is. That is, the string '1' rather than the integer 1 is in your graph.
This is because when you read the file in, it interprets everything as strings. The documentation shows the optional arguments: read_edgelist(path, comments='#', delimiter=None, create_using=None, nodetype=None, data=True, edgetype=None, encoding='utf-8'). Notice the optional argument nodetype. The documentation says:
nodetype (int, float, str, Python type, optional) – Convert node data
from strings to specified type
So do your call as
G=nx.read_edgelist(fh, nodetype = int)
