Disconnect the pilot tube from the valve and pass a thin wire through it to make sure it is not blocked. Spiders have been known to nest in tubes off-season. If the tube is clear and the gas still won't flow through then the valve block probably needs to be replaced. If the high temperature limit has been tripped the valve will have to be replaced as high limit safety does not reset.
I believe the valve block needs to be replaced. I do not think they can be repaired but I may be mistaken on that. I am in the US an cannot advise you on local suppliers.I believe the valve block needs to be replaced. I do not think they can be repaired but I may be mistaken on that.
